Question

A ball is thrown straight up with enough speed so that it is in the air for several seconds. Assume the positive direction is upwards. Part A: What is its velocity 0.50 s before it reaches its highest point? Part B: What is the change in its velocity, v, during this 0.50 s interval? Part C: What is its velocity 0.50 s after it reaches its highest point? Part D: What is the change in velocity, v, during this 0.50 s interval? Part E: What is the change in velocity, v, during the 1.0 s interval from 0.50 s before the highest point to 0.50 s after the highest point? (Caution: We are talking about velocity, not speed.) Part F: What is the acceleration of the ball during any of these time intervals and at the moment the ball has zero velocity?
