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?
