4.3 Abrupt Acceleration: A Bouncing Ball Imagine dropping a very bouncy ball straight down. It hits the ground and bounces back up again. Assume it is so elastic that it reaches essentially the same height from which you dropped it. Question 29) Draw a graph of the ball's position-versus-time during the interval when it is drop- ping toward the ground. Assume that the ball began dropping from a positive height at time t = 0 and that it reaches the ground at y = 0 and t = 4 s. (Each horizontal unit on the graph is 1 s.) yA Question 30) Draw a graph of the ball's position-versus-time during the interval when it has just bounced up as it rises back toward a maximum height. Make sure to start this graph at t = 4 s. Blues yA Question 31) Draw a graph of the ball's velocity-versus-time during the full time interval from when it began dropping to the time it bounced up and reached its maximum height after the bounce. Label the portions of the graph where the ball is speeding up and slowing down. 18Question 32) How is acceleration represented on the velocity-time graph of the bounce?
