A basketball player drops a 0.5 kg basketball vertically so that it is traveling at 5.0 m/s when it reaches the floor. The ball rebounds upward at a speed of 3.2 m/s. The ball is in contact with the ground for a time of 10 ms. Draw a sketch of the situation, labeling all of the physical quantities given in the problem. Identify your system in the sketch. Make sure all relevant moments in time are shown in your sketch.
