Atennis ball is shot straight up from the ground. after traveling 4.00 m, the ball passes a 4.00 m high window and then continues straight up until it loses all its upward velocity and falls to the ground. during the last second of its flight before it hits the ground, the ball drops 20.0 m. a) what is the maximum height above the ground reached by the ball?
b) what is the total time for the ball’s flight?
c) when the ball is travelling upward, during what time interval is the ball passing the window?
