Question

 

Suppose that you measure the velocity of a 0.015-kg superball just before it hits the floor and find that its velocity is downward with a magnitude of 4.5 m/s. You also measure its velocity just after it hits the floor and find that it is upward with a magnitude of 3.9 m/s. What is the change in momentum of Earth as a result of the collision with the superball?
