A superball with a mass =61.6 g is dropped from a height =2.03 m. It hits the floor and then rebounds to a new height that is 88.5% of the initial height. Use upward as the positive direction. (a) What is the momentum change of the ball during its collision with the floor? (b) Suppose you drop a ball of putty of the same mass from the same height and the putty sticks to the floor. What then would be the second ball's momentum change during its collision with the floor?
