Indian Institute of Technology 2023 JEE Physics Q1 solution

B

A basketball with an initial speed of 3 meters per second impacts a hard floor at the sixty degree angle as shown below. If the collision has a coefficient of restitution of 0.8, what is the expected speed and angle of the basketball after the impact?

Figure 10.2.210.2.2: problem diagram for Example 10.2.110.2.1. A basketball with a known initial velocity bounces off a floor with a known coefficient of restitution.
