According to the conservation of momentum, if a smaller football player collides with a
much larger football player, what can be said about the movement of each player after
the collision?

Answers

Although the bigger football player will move, his speed will be substantially slower than the smaller players due to his greater mass.

According to the law of conservation of momentum, The overall momentum of two or more bodies acting on one another in an isolated system stays constant unless an external force is introduced. As a result, momentum cannot be gained or lost.

When a collision occurs, the point of impact is generated by two equal and opposing forces. The heavier mass will be forced to accelerate by the force applied to it, whereas the smaller mass will be forced to slow down by the force applied to it.

Because of their greater mass, larger masses will accelerate more slowly, reducing their velocity.

What is the vertical distance, in meters, from where the projectile was launched to where it hits the target?

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

  = 19.734m

Hence, the horizontal distance is 82.455m and vertical distance is 19.734m

Answer in units of m.

Answers

The package strike the ground relative to the point directly below it was released at 213.3m.

Equation:

Given values,

Velocity of plane 45 m/s

Acceleration due to gravity 9.8 m/s²

horizontal component of plane velocity is

ux = 45 m/s

Vertical component is zero

In the same way

ay = - 9.8  m/s²

ax = .0 m/s^2

Motion in y direction = -110 m

From equation of motion time of flight is

d = u x t + 1/2 at²

where,

d is distance

u is velocity initial

a is acceleration

t is time

So, putting values

-110 = 0 + 1/2 (-9.8)t²

-110 = -4.9t²

t² = 110 / -4.9

t² = 22.45

t = √22.45

t = 4.74

Motion in x direction,

d = u x t + 1/2 at²

d = ( 45 x 4.74) + 1/2 (0) 4.74²

d = 213.3 + 0

So the friction on the shoe does rely on the load. So the slope of the graph represents the coefficient of friction. Kinetic friction importance is directly proportional to the regular pressure magnitude and the roughness between the sliding surfaces.

What is the time period?

Time period in periodic oscillation refers to the time taken by the system to complete one oscillation.

Given:

Time period of the oscillation = 0.5 seconds

Amplitude of the oscillation = 2 cm

For determining frequency we use the formula of frequency.

f = 2π/T

Where,

f is the frequency of the oscillation

T is the time period of the oscillation

On substituting values we get,

Frequency (f) = 1/0.5

Frequency (f) = 2 Hertz

For determining maximum acceleration we use,

a = A × w × w

Where,

a is the acceleration

A is amplitude of the SHM

w is the angular frequency

Now,

a = A × w × w

a = 0.02 × 12.4× 12.4

a = 3 u

Answers

Yes, the stars going supernova will have impact on allowing life to exist in nearby planets.

When a star goes supernova, a large amount of radiation is emitted. So, if a nearby planet inhabiting life has a ozone layer, it will be depleted. This results in increased harmful radiation levels on the ground. There will be mutations in organisms that can survive the radiations. Those that are not strong will die.

A supernova is the explosion of a star. This phenomenon happens when a star's nuclear fuel in its core runs out. As a result the pressure created by the burning in its core becomes completely null. Thus the gravity is only force acting, so the star collapses on itself emitting huge quantities of light and harmful radiation.

(Desperately need help with Part 2)

Answers

Answer:

Final speed of car = 9.834 m/s

Displacement = 0.035 km

Explanation:

Part 1

Final velocity, v of an object moving with an acceleration a m/s² for t seconds and an initial velocity u m/s is given by the formula
v = u + at m/s


[tex]\textrm{Initial velocity } u = 22.1 km/h\\\\\textrm{Convert this to m/s:}\\\\\textrm{1 km/h = 1000m/3600 s}\\\\ 22.1 km/h = 22.1 x 1000/3600 = 6.139 m/s\\\\\boxed{\textrm{Final velocity } v = u + at = 6.138 + 0.84 x 4.4 = 9.834 m/s}[/tex]

Displacement s in m for a constant acceleration of a m/s² for a time t seconds is given by the formula:
[tex]x = ut+\dfrac{1}{2}at^2[/tex]
where u is initial velocity

Plugging in the values we get
[tex]s = 6.139\cdot 4.4 + \dfrac{1}{2}\cdot0.84\cdot (4.4)^2 = 35.143 \;\mathrm {meters}[/tex]
35.143 meters = 35.143/1000 =  0.035 km


Answer:

1)  9.83 m/s (2 d.p.)

2)  0.04 km (2 d.p.)

Explanation:

Constant Acceleration Equations (SUVAT)

[tex]\boxed{\begin{array}{c}\begin{aligned}v&=u+at\\\\s&=ut+\dfrac{1}{2}at^2\\\\ s&=\left(\dfrac{u+v}{2}\right)t\\\\v^2&=u^2+2as\\\\s&=vt-\dfrac{1}{2}at^2\end{aligned}\end{array}} \quad \boxed{\begin{minipage}{4.6 cm}$s$ = displacement in m\\\\$u$ = initial velocity in ms$^{-1}$\\\\$v$ = final velocity in ms$^{-1}$\\\\$a$ = acceleration in ms$^{-2}$\\\\$t$ = time in s (seconds)\end{minipage}}[/tex]  

When using SUVAT, assume the object is modeled as a particle and that acceleration is constant.

Part 1

Given:

u = 22.1 km/ha = 0.84 m/s²t = 4.4 s

Convert km/h into m/s by dividing by 3.6:

[tex]\implies \sf 22.1\;km/h=\dfrac{22.1}{3.6}\;m/s[/tex]

Substitute the given values into the formula and solve for v:

[tex]\begin{aligned}v&=u+at\\\implies v & = \dfrac{22.1}{3.6}+0.84(4.4)\\v & = 6.1388...+3.696\\v & = 9.834888...\\v & = 9.83 \sf \;m/s\;(2\:d.p.)\end{aligned}[/tex]

Therefore, the final speed of the car was 9.83 m/s (2 d.p.).

Part 2

Substitute the given values into the formula and solve for s, remembering to use the initial velocity in m/s:

[tex]\begin{aligned}s & = ut+\dfrac{1}{2}at^2\\\implies s &=\dfrac{22.1}{3.6}(4.4)+\dfrac{1}{2}(0.84)(4.4)^2\\s &=27.0111...+8.1312\\s &=35.1423111...\sf m\end{aligned}[/tex]

Convert meters into kilometers by dividing by 1000:

[tex]\implies \dfrac{35.1423111...}{1000}=0.0351423111...=0.04 \sf \; km\;(2\:d.p.)[/tex]

Therefore, the displacement of the car after 4.4 s was 0.04 km (2 d.p.).

= 6400 m³ / 20 m³

= 320

(c) Now,

Density, d = 0.72 g/cm³ = 720 kg/m³

The empty mass is 20 metric tons which is equal to 20 ×10³ kg.

Therefore, the gross mass of each truck will be

m = 20 ×10³ kg + 720 kg/m³ × 20 m³

m = 20000 kg + 14400 kg

m = 34400 kg

A reconnaissance plane flies 404 km awayfrom its base at 730 m/s, then flies back to its base at 1095 m/s.What is it’s average speed?
Answer in units of m/s

Answers

The average speed of the plane is 875.999 m/s.

Average speed can be defined as the ratio of total distanced travelled by the object to that of total time taken to cover the distance.

Mathematically, Average speed = Av = [tex]\frac{Total Distance}{Total Time}[/tex]

According to the question,

Speed of the plane away from its base V₁ = 730 m/s

Speed of the plane when it flies back V₂ = 1095 m/s

Plane flies the distance D = 404 km

Total Distance covered by the plane S = 404 * 2 km

(because the distance travelled by the plane when going away from the base and then flying back to the base is same)

Therefore S = 808 km = 808 ˣ 10³ m

Time taken by the plane while flying away from the base T₁ = [tex]\frac{D}{V1}[/tex]

T₁ =  [tex]\frac{404000}{730}[/tex] = 553.425 s

Time taken by the plane while flying back to the base T₂ = [tex]\frac{D}{V2}[/tex]

T₂ =  [tex]\frac{404000}{1095}[/tex] = 368.949s

Total Time T = T₁ + T₂ = 922.375 s

Therefore  Av = [tex]\frac{Total Distance}{Total Time}[/tex]

= [tex]\frac{D}{T}[/tex] m/s

=  [tex]\frac{808000}{922.375}[/tex]  m/s

= 875.999 m/s

The average speed of the plane will be 875.999 m/s.

A transverse wave can be graphed as position vs. time or y-position vs. x-position. If
you want to determine the wavelength of a transverse wave, which graph should
you use? Explain

Answers

To determine the wavelength of a transverse wave, we use the graph of  y-position vs. x-position.

What is a transverse wave?

A transverse wave is a wave in which the direction of propagation of the wave is perpendicular to the direction of the disturbance causing the wave.

Plotting a transverse wave,

the y - direction represents the direction of disturbance of the wave, the x - direction represents the direction of propagation of the wave and t axis represents the time of travel of the wave

Now, we can have two graphs namely,

position vs. time or y-position vs. x-position.Which graph will we use to determine the wavelength of a transverse wave.

If we plot a cycle of each graph above, we see that position is plotted against time and y-position is plotted against x-position.

We note that the x - position is the direction of travel of the wave in which we measure its wavength. Since the wavelength is the x - position after one cycle, so, we use the graph of y-position vs. x-position to find its wavelength.

So, to determine the wavelength of a transverse wave, we use the graph of  y-position vs. x-position.
