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.
