A golf ball of mass m = 0.12 kg is dropped from a height h. It interacts with the floor for t = 0.185 s, and applies a force of F = 11.5 N to the floor when it elastically collides with it. Randomized Variables
m = 0.12 kg
t = 0.185 s
F= 11.5 N

Part (a) Write an expression for the ball's velocity, v, in terms of the variables m, t, and F, just after it rebounds from the floor. (Hint: The fact that the collision is elastic is important when solving this problem.)

Part (b) What is the magnitude of the ball's velocity v, in meters per second, right after it rebounds?

How high h, in meters, will the ball travel on the rebound?
