A ball is tossed in the air. It moves upward, reaches its highest point and falls back downward. Sketch the velocity time and acceleration time graph for the ball from the moment it leaves the throwers hand until the moment just before it reaches her hand again. Consider the positive direction to be upward.

A ball of mass 1.5 kg is thrown upward. It leaves the thrower's hand with a velocity of 10 m/s. The following questions refer to the motion after the ball leaves the thrower's hand. Assume that the upward direction is positive.
A. How long before the ball returns to the throwers hand?
B. What is final velocity of the ball just before it reaches the hand?
C. What is the change in momentum of the ball?
D. What is the impulse calculated from the change of momentum?
E. from the impulse, find the average force acting on the ball. What causes the force?
