At the moment when a shotputter releases a 5.00 kg shot, the shot is 3.00 m above the ground and travelling at 15.0 m/s. It reaches a maximum height of 8.00 m above the ground and then falls to the ground. If air resistance is negligible, Required:
a. What was the potential energy of the shot as it left the hand relative to the ground?
b. What was the kinetic energy of the shot as it left the hand?
c. What was the total energy of the shot as it left the hand?
d. What was the total energy of the shot as it reached its maximum height?
