4.5. A 0.50 kg basketball bounces upward from the floor (vertically) at a speed of 7.2 m/s. Let's assume that no one touches the ball as it bounces upward, reaches some maximum height, and falls back down to the floor (to bounce again). (a) How much time passes before the ball hits the floor again? (b) What is the maximum height above the floor the ball reaches?
