Question

a) What is the speed of the basketball immediately before the collision, i.e. just before making
contact with the ground? In other words, what is v,?
b) What is the speed of the basketball immediately after the collision, i.e. just after the ball has
decompressed? In other words, what is v;?
c) Is the collision of the basketball with the ground an elastic or inelastic collision? Explain
your answer and support it with calculations.
d) Calculate the average force exerted by the ground on the basketball during the collision. In
other words, calculate the average normal force during the collision.

A basketball of mass m = 0.65 kg is released from rest at a height h;
hits the ground, and bounces up to a maximum height hf
with the ground takes 0.2 seconds. This is the time that the basketball is in contact with the
ground. During this time, the basketball is compressed as it slows down, and then is
decompressed as it bounces up. Figure 6 shows the basketball at seven distinct stages of its
motion. Suppose air resistance is negligible. Note: This problem continues on the next page.
