Chapter 2, Problem 75P
* Oliver drops a tennis ball from a certain height above a concrete floor. Figure P2.75 shows the velocity-versus-time graph of the ball’s motion from the moment the ball is released to the moment the ball reaches its maximum height after bouncing up from the floor. (a) How is the y-axis directed: up or down? (b) Determine the initial height from which the ball is released and the final height to which the ball bounces. (c) Determine the average speed of the ball during the downward motion.
