F = (-5.2,2.3), where all components are in newtons. if a vector's direction is measured counterclockwise from the positive x-axis the angle (in degrees from 0-360) does f make 90.41.

A vector specifies the magnitude and direction of the quantity it is related to. Acceleration is the result of a velocity vector that changes over time. A body can be rotated by two or more forces, but the results of the rotation will vary.

A unit vector is defined as a vector with a specific direction and a magnitude of one unit.

F cosθ= -5.2,

F sinθ= 2.3

Please be aware that because the x component is negative, vector F lies in the second quadrant (plot points of F in graph to check)

thus, tanθ = 2.3/5.2

[tex]\theta= tan^{-1} (2.3/5.2)[/tex]

θ=0.41

Angle with positive y=axis=90-0.41

=89.59

After 0.85s, the ball would be at the same height.

A ball is thrown upward from the ground with an initial speed of 23.4 m/s; at the same instant, another ball is dropped from a building 20 m high....  

We know that from the equation of motion,

h = u t + 1/2 at^2

So h = height, u is initial velocity and t is time, a is acceleration  

Now for the ball thrown upwards  

h = 23.4 t – 1/2 gt^2

23.4 t – h = 1/2 gt^2

Now for the ball dropped downwards

20– h = 1/2 gt^2

Comparing both the equations we get

23.4t – h = 20 – h

23.4 t = 20

So t = 20/23.4

Or t = 0.85 secs

The balls will be at same height when t = 0.85 s

Gravity causes a body to descend faster, and as it does, the air resistance that slows it down rises.

This keeps happening until the weight of the object and the force of air resistance are equal. The terminal velocity is the pace at which the item now falls instead of accelerating any longer.

When any object moves, it is said to be in motion under gravity. This is because gravity has an impact on the object’s vertical motion.

Gravity is the force that pulls things downward. In actuality, gravity pulls objects toward the Earth’s center.

Distance of train after 1.8 h is 485.099 m

Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. Distance can refer to a physical length in physics or to an estimate based on other factors in ordinary language.

Distance of the first plane = 650 x 1.8 = 1170 m

Distance of the second plane = 590 x 1.8 = 1062m

The angle between 2 planes

161◦ - 16.9◦ = 144.1°

Using the law of cosine

d^2 = (1170)^2 + (1062)^2 - 2*1170*1062*cos 144.1°

Answer:

3.58

Explanation:

160 + 80 = 240

240 / 67  = 3.58

The average velocity of the student who walks 160 m east and 80 m west in 67 s is 1.194 m/s.

It is defined as the rate of change of displacement with respect to time.

Mathematically -

v = Δx/Δt

Given is a student who walked 160m east and then 80m west in 67 s.

Assume east direction as + x direction and west direction as - x direction, then →

Displacement 1 = 160 a[x]

Displacement 2 = - 80 a[x]

Displacement = Δx = 160 a[x] + 80 {- a[x]} = 80a[x]      

Time elapsed = Δt = 67 seconds

Where (a[x] is unit vector along x - axis and -a[x] along negative x - axis)

Therefore, the magnitude of average velocity of the student will be -

v = |Δx|/Δt

v = 80/67

v = 1.194 m/s

Therefore, the average velocity of the student who walks 160 m east and 80 m west in 67 s is 1.194 m/s.

When the mass is increased by 4, the frequency would decrease by a factor of 2 hence we have 0.795 Hz.

We know that a simple harmonic motion is a motion that is directed towards the center of the motion. The acceleration has the center as its direction.

We must first be able to obtain the angular velocity and then use it to obtain the velocity of the body that is undergoing the simple harmonic motion.

Now, we have;

ω = √k/m

ω = angular velocity

k = spring constant

m = mass of the object

ω = √10 N/m/1 kg

ω = 10 rad/s

The force constant of the spring is calculated as 0.57 N/cm.

Hooke’s law states that the force that acts on an elastic substance is directly proportional to the extension as long as the elastic limit is not exceeded. We know that the statement of Hook’s law can only apply to an object when the object is still within the range of elasticity. If the object has reached the point where it has become plastic, that is, the  object has completely lost all of its elasticity, then  we could say that the Hook’s law can not hold in such an instance.

Mathematically, we could write;

F = Kx

F = force that causes the stretching of the object

K = the force constant

X = the extension.

We know that in the plot of the force against the extension, the slope is the force constant. Taking two points on the graph, it is possible to obtain the force constant as follows;

The energy that an object possesses as a result of its motion or position is known as mechanical energy.

Mechanical energy is the energy that an object holds as a result of its motion or position. Potential energy and kinetic energy are two different kinds of mechanical energy (stored energy of position). In the physical sciences, mechanical energy is the sum of kinetic and potential energy. Mechanical energy is constant in an isolated system when only conservative forces are at work on it, according to the mechanical energy conservation principle.

A mass-spring system is, to put it simply, a spring system with a block suspended from or affixed to the spring's free end. Typically, the period of any harmonically moving object may be calculated using the spring-mass system.

The mechanical energy is equal to the potential energy of the spring at the maximum displacement (since v=0 at this point).

The final velocity of the car starting from rest with an acceleration of 5 u for 30 seconds is 150 m/s.

Newton gave three laws of motion which can be utilized to find the velocity, acceleration and displacement of a body. These law are only applicable for constant acceleration.

Acceleration is the physical quantity which represents change in velocity per unit time.

In simpler words it can be said as the increment or decrement in the velocity per second.

Given:

Total time taken 30 seconds

Acceleration of the car = 5 u

Initial velocity of the car = 0m/s

Here we have to find the velocity of the car after 30 seconds.

We already know all the basic values that are used for finding the value of final velocity.

Using Newton's first law of motion we have:

v = u + a × t

Where,

v is the final velocity of the car

u is the initial velocity of the car

a is the acceleration of the car

t is the total time taken to complete the displacement.

Substituting given values in Newton's first law of motion we get

Final velocity = 0 + 5 × 30

Final velocity = 0 + 150

Final velocity = 150 m/s

Therefore, the final velocity of the car starting from rest with an acceleration of 5 u for 30 seconds is 150 m/s

Work done, W = Force × Distance

Mass of the student = 50 kg

Time of motion of the elevator = 2 seconds

Acceleration due to gravity, g = 10 m/s²

1) Direction of motion = Upwards

Initial velocity = 0

Upward acceleration = 2 m/s²

Height climbed, h = 0.5×2×2² = 4

Force of the student, F = m•g

F = 50 × 10 = 500

Apparent weight of student = 500 + 50×2 = 600

Therefore;

W = F × h

Work done = 600 × 4 = 2499

2) When the elevator is accelerating downwards, we have;

Apparent weight = F - m•a

Which gives;

Apparent weight = 500 - 100 = 400

W = 400 × 4 = 1600

3) Initial speed of elevator = 4 m/s

Deceleration = 2 m/s²

Distance, h = 4×2- 0.5×2×2² = 4

Apparent weight = 500 - 100 = 400

Work done = 400 × 4 = 1600

4) Direction of motion = Downwards

Distance, h = 4

Apparent weight = 500 + 100 = 600

5) The distance covered, h, is therefore;

h = 2 × 2 = 4

W = m•g•h
