and
B = 2 m.
What are the largest and the smallest values (in m) of the magnitude of the resultant
R = A + B?

Answers

The largest resultant vector is 47 m and the smallest resultant vector is 43 m.

What is resultant of a vector?

The resultant of a vector is obtained by adding the two vectors together.

The resultant vector  can be any single vector that can effectively describe the other vectors.

The resultant vector is calculated using the following formulas;

R² = A² + B² - 2AB cosθ

Largest resultant vector

R² = (45)² + (2)² - 2(45 x 2) cos(180)

R² = 2209

R = √2209

R = 47 m

Smallest resultant vector

R² = (45)² + (2)² - 2(45 x 2) cos(0)

R² = 1849

R = √1849

R = 43 m

Thus, the largest resultant vector is 47 m and the smallest resultant vector is 43 m.

(b) Determine the angle between the positive x axis and the total force that the cockpit seat exerts on the 76- kg pilot, measured counterclockwise.

Answers

a. The magnitude of the total force that the cockpit seat exerts on the 76- kg pilot is 288.8 N.

b. The angle between the positive x axis and the total force that the cockpit seat exerts on the 76- kg pilot is 67⁰.

Force exerted on the pilot by the cockpit

The force exerted on the pilot by the cockpit is calculated as follows;

F = ma

where;

m is mass of the pilot

a is acceleration of the jet

F = 3.8 m/s² x 76 kg

F = 288.8 N

The total force exerted on the pilot is equal to the normal reaction of the pilot.

F = Fn

F = mg cosθ

cos θ = F/mg

cos θ = (288.8) / (76 x 9.8)

Give your answer in what fraction or multiple of your earthly weight.

Answers

Mass on the planet would be 10/3 times the mass on Earth weigh on this new planet.

How do you define mass?

A quantitative measure of the fundamental characteristic of all matter, inertia. In essence, it's the resistance of a mass of matter to changing its direction or speed in reaction to the force applied to it. The much more weight a body has, the less change an applied force produces.

Briefing:

Let the mass of Earth = Me

Let the radius of Earth = Re

Mass of the planet, Mp = 10Me

Radius of the planet, Rp = 3Re

Weight on other planet, W = ?

Weight on planets is determined by the gravitational force

Gravitational force, F = GMm/r²

where, G = gravitational constant

M = Mass of the planet

m = our mass

r = radius of the planet

Gravitational force on Earth:

F = G X Me X ma/ Re².....eq (1) (ma = mass on earth)

Gravitational force on planet :

F = G X 10Me X mₓ/ (3Re)²....eq (2) (mx = mass on other planet)

Dividing both the equations, we get

mx = 10/3ma

Therefore, mass on the planet would be 10/3 times the mass on Earth.

Destiny is eating lunch at her favorite cafe when her friend Jada calls and says she wants to meet her. Jada is calling from a city 65 miles away and wants to meet Destiny somewhere between the two locations. Jada says she will start driving right away, but Destiny needs 10 min to finish her lunch before she can begin driving.

Jada plans to drive at 60 mph, whereas Destiny usually averages about 80 mph. Ignore acceleration and assume the highway is a straight line.

Answers

The time taken for Jada's and Destiny's travel are 0.5595hour and 0.3928 hour

Let us consider distance for which both had to travel be equal

Let this time be 't'

The total distance between them is 65 miles

It is given that speed of Jada and Destiny are 60 and 80 mph

It is also given Destiny starts the journey 10 minutes later, hence her time be t-10 mins

But as all units are in hour , we must convert 10 mins to hour,

10 mins = 0.1667 hours

there Destiny's time of travel = t - 0.1667

We know that distance = speed x time

Therefore, total distance = distance travelled by Jada+ Distance travelled by Destiny

65 = 60 x t + 80 x(t-0.1667)

65 = 60t + 80t - 13.336

78.336 = 140 t

t = 78.336/140 = 0.5595hr

t= 0.5595 hour

Time taken for Jada's travel = 0.5595 hours

Time taken for Destiny's travel = t-0.1667 =0.5595-0.1667  =0.3928 hour

Newton's Second Law of Motion says that acceleration (gaining speed) happens when a force acts on a mass (object). Riding your bicycle is a good example of this law of motion at work. Your bicycle is the mass. Your leg muscles pushing on the pedals of your bicycle is the force. Newton's second law is a quantitative description of the changes that a force can produce in the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.

An 8.50 m long ladder leans against the side of a building. The ladder is initially inclined at an angle of 47.0° to the horizontal. The base of the ladder is then moved 0.82 m closer to the building. At what angle is the ladder now inclined with respect to the horizonta

Answers

The angle of the ladder inclined with respect to the horizontal after being moved a distance of 0.82 m closer to the building is 53.84°

cos θ = Adjacent side / Hypotenuse

θ[tex]_{1}[/tex] = 47°

Hypotenuse = Length of ladder = 8.5 m

cos 47° = Adjacent side / 8.5

Adjacent side = Initial distance of base of ladder from the building = 5.8 m

Adjacent side 2 = Final distance of base of ladder from the building

Adjacent side 2 = 5.8 - 0.82 = 4.98 m

cos θ[tex]_{2}[/tex] = Adjacent side 2 / Hypotenuse

cos θ[tex]_{2}[/tex] = 4.98 / 8.5 = 0.59

θ[tex]_{2}[/tex] = [tex]cos^{-1}[/tex] ( 0.59 )

θ[tex]_{2}[/tex] = 53.84°

The formula used above is one of trigonometric ratios. Trigonometric ratios can used only in a right angled triangle where one of the angles in at 90 degrees and the other two angles are less than 90 degrees.

The average velocity for completing three rounds of the basketball court would be zero as initial and final position would be zero and the average speed would be 3.28 m/s.

What is average velocity ?

Average velocity is defined as the total displacement divided by the total time take to compete the total displacement.

What is average speed ?

Average speed is defined as the total distance divided by the total time take to compete the total distance.

Given:

Side of the baseball court = 100 meter

Total time taken to complete three rounds of the basketball court = 375 seconds

Total distance traveled by the player can be measured using the given side of the basketball court.

First we will find the parameter of the court,

Parameter of the court = 4 times the side of basketball court

Parameter of the basketball court = 4 × 100

Parameter of the basketball court = 400 metre

The player goes for 3 rounds of the basketball court which makes the total distance three times the parameter of the basketball court.

Total distance traveled by the basketball player = 3 × 400

Total distance traveled by the basketball player = 1200 metre

Average velocity is displacement divided by time taken.

Total displacement = 0 metre

As the player reaches the same position from where he started so the total displacement is zero.

Therefore, average velocity = 0/365

What are Newton's law of motion?

Newton's laws of motion are three basic laws of classical mechanics that describe the relationship between the motion of an object and the forces acting on it.

Given:

Initial velocity of the model rocket = 50m/s

Constant acceleration of rocket = 2 u

Height to which acceleration was in account= 150m

First we need to find the final velocity at 150 metres.

We can do so simply by using Newton's third law of motion,

Velocity at 150 metre = under root (2500 + 600)

Velocity at 150 meter = 55.7

Maximum height height reached by the model rocket can be find using the equation for max height.

.i.e. maximum height = u × u/2g + initial distance traveled

maximum height = 55.7×55.7/19.6 + 150

maximum height = 156.5 + 150

Maximum height= 300.5 m

Time taken to reach maximum height = time taken before acceleration stops + time after which acceleration stops

Time taken to reach maximum height = 5.7/2 + 55.7/9.8

Time taken to reach maximum height = 2.85 + 5.7

Time taken to reach maximum height = 8.5 seconds

The rocket will be air for the time = time to reach maximum height + time to fall to the ground

The rocket will be air for the time = 8.5+ 7.8

The rocket will be air for the time = 17.3 seconds.

Therefore, the maximum height reached by the model rocket is 300.5 meter, time to reach maximum height is 8.5 seconds and the time for which the model rocket was in air is 17.3 seconds.

The force between them when they are separated instead by 12 cm is 5 N.

The force between them when charge A is doubled is 40 N.

The force becomes 80 N  if charge B is doubled as well.

Force between two charges

The force between two charge is determined from Coulomb's law of electrostatic force.

f = kq²/r²

when the distance, r is double the force reduces by 4;

f = kq²/(2r)²

f =  kq²/4r²

New attractive force when the distance is 12cm, = 20 N/4 = 5 N

Magnitude of force when one of the charge is double

f =  k(2q₁)(q₂)/r²

f =  2k(q₁q₂)/r²

New force = 2 x 20 N = 40 N

When charge B is doubled as well

f =  k(2q₁)(2q₂)/r²

f =  4k(q₁q₂)/r²

New force = 4 x 20 N = 80 N

Thus, the force between them when they are separated instead by 12 cm is 5 N.

Answers

The horizontal distance is 82.455m and vertical distance is 19.734m

Let us first find the x and y components of velocity

The velocity is given to be 41m/s

the angle of projectile is given to be 29 degree

The x component of velocity = Vx =v cosα =41 x 0.8746 =35.85 m/s

The y component of velocity= Vy= v sinα=41 x 0.484 =19.85 m/s

The horizontal displacement x= Vxt = 35.85 x 2.3 =82.455 m

To solve for vertical distance y = Vyt+1.2at^2

y = 19.85 x 2.3 + 1/2 x -9.8 m/s^2 x 2.3

Except for the fact that the distance did not rise linearly but rather more quadratically, the results support the theory. The results showed that the distance rose as the weight of the trebuchet's counterweight was increased in steps of 5 kilograms, starting at 20 kilograms and ending at 200 kilograms.

Each time, the projectiles were launched from the trebuchet at a 45-degree angle, and their distances typically followed the equation -8.1551E-4x2 +.304388x + 8.12756 (where x is the mass of the counterweight). The graph was thought to be more quadratic than linear because gravity has more time to work against the projectile and pull it down to the earth the longer it is in the air. Therefore, as additional mass is applied and the projectile is in the air for a longer period of time, the projectile distances would not grow as quickly. These findings back up Newton's Third Law of Motion as well as earlier, historical investigations.

Thus, Thomas should launch the trebuchet at a 45º angle to get the farthest thrown projectile.

Suppose an electron in some atom absorbs energy and transitions from level 1 up to level 4. Which of the following is a true statement regarding the electron transitions back down to level 1?
a. It must transition from 4 to 3, then 3 to 2, then 2 to 1. All downward transitions are one step at a time.
b. 4 to 2, followed by 2 to 1, is possible. Downward transitions can be any number of levels.
c. It can go from 4 to 1 only. The downward transition must match the upward one.

Answers

b. 4 to 2, followed by 2 to 1, is possible. Downward transitions can be any number of levels.

Downward transitions can indeed be any number of levels at a time. Together with the rule that each downward transition produces a photon of a particular color, you can see why each element has a unique the emission spectrum.

given that vector c=a+b, indicate the conditions that A and B have to meet in order for c to have the largest and smallest possible magnitudes

Answers

A Vector is a quantity which has both magnitude as well as direction.

vectors follow parallelogram law of addition and uses cosine of the angle between the vectors.

The addition of two vectors, i.e. c, is given by the formula

c=[tex]\sqrt{a^2+b^2+2abcos\alpha }[/tex]

where [tex]\alpha[/tex] is the angle between the vectors

now we know that maximum value of cos[tex]\alpha[/tex] can be is 1

and minimum value of cos [tex]\alpha[/tex] can be-1

now the maximum value cos[tex]\alpha[/tex] is 1 at the angle of π/2

and the minimum value of cosα is -1 is at the angle of -π

Therefore, A and B should have 0 degree between them and in the same direction to have the maximum value

there fore they should be in same direction and 0 degree meaning they should be on same line

A and B will have minimum value when the angle is 180 degree which means they should be on same line and be inn opposite direction to each other.

The "Screaming Swing" is a carnival ride that is - not surprisingly - a giant swing. It's actually two swings moving in opposite directions. At the bottom of its arc, a rider in one swing is moving at 34 m/s with respect to the ground in a 46- m -diameter circle. The rider in the other swing is moving in a similar circle at the same speed, but in the exact opposite direction. What is the acceleration, in m/s2 , that riders experience?

Answers

The acceleration, in m/s² , that riders experience is 50.3 m/s²

What is the acceleration, in m/s² , that riders experience?

Since the riders move in a circle, they undergo circular motion and will have a centripetal acceleration.

So, the centripetal acceleration, is given by a = v²/r where

v = speed of rider andr = radius of circle

Given that a rider in one swing is moving at 34 m/s with respect to the ground in a 46- m -diameter circle. We have that

v = speed of rider = 34 m/s and r = radius of circle = 46/2 = 23 m

So, substituting the values of the variables into the equation for the acceleration, we have

a = v²/r

a = (34 m/s)²/23 m

a = 1156 m²/s²/23 m

a = 50.26 m/s²

a ≅ 50.3 m/s²

So, the acceleration, in m/s² , that riders experience is 50.3 m/s²
