Solve the all parts of given problem:

Problem: A girl throws a 0.2 kg ball a distance of 6m straight up in the air (assume no air resistance).

Part A: What is the kinetic energy of the ball as it leaves the girls hand?

Part B: How much work does the girl do in throwing the ball?

Part C: If the girl's arm muscle contracted a distance of 0.050 m while throwing the ball, what is the average force exerted by the muscle?

I need help to determine the kinetic energy of the ball as it leaves the girls hand.
