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 the velocity of the ball when it reaches its highest point Part B - What is its velocity 0.70s before it reaches its highest point? Part C - What is the change in its velocity, v, during this 0.70s interval? Part D - What is its velocity 0.70s after it reaches its highest point? Part E - What is the change in velocity, v, during this 0.70s interval? Part F - What is the change in velocity, v, during the 1.4s interval from 0.70s before the highest point is 0.70s after the highest point? (Caution: we are talking about velocity not speed) Part G - What is the acceleration of the ball during any of these time interavals and at the moment the ball has zero velocity?
