Answer:
Explanation:
= Initial momentum of the pin = 13 kg m/s
= Initial momentum of the ball = 18 kg m/s
= Momentum of the ball after hit
= Angle ball makes with the horizontal after hitting the pin
= Angle the pin makes with the horizotal after getting hit by the ball
Momentum in the x direction
Momentum in the y direction
The pin's resultant velocity is
The pin's resultant direction is below the horizontal or to the right.
Meteoroid
Streak of light
Reached earth's atmosphere
Explanation:
The celestial object is called a meteoroid because it is a producing a streak of light and has not yet reached the earth's atmosphere.
Meteoroids are called shooting stars due to the beautiful trail of light they leave in their wake.
- A meteoroid is a celestial object that ranges from a few grains to some meters wide.
- They are usually solid. They can be rocky, metallic or both.
- A meteoroid is still in space and has not reached the earth atmosphere.
- Some meteoroids are destroyed when they get to the atmosphere and are called meteors.
- Those that penetrates and reaches the surface are called meteorites.

I’m not sure what your asking explain
F = 2820.1 N
Explanation:
Let the (+)x-axis be up along the slope. The component of the weight of the crate along the slope is -mgsin15° (pointing down the slope). The force that keeps the crate from sliding is F. Therefore, we can write Newton's 2nd law along the x-axis as
Fnet = ma = 0 (a = 0 no sliding)
= F - mgsin15°
= 0
or
F = mgsin15°
= (120 kg)(9.8 m/s^2)sin15°
= 2820.1 N
