Solve the all parts of given question:

Question: A fast pitch softball player does a "windmill" pitch, moving her hand through a vertical circular arc to pitch a ball at 72 mph. The 0.19kg ball is 52cm from the pivot point at her shoulder.

Part I: Just before the ball leaves her hand, what is its centripetal acceleration?

Part II: At the lowest point of the circle the ball has reached its maximum speed. What is the magnitude of the force her hand exerts on the ball at this point?

Part III: At the lowest point of the circle the ball has reached its maximum speed. What is the direction of the force her hand exerts on the ball at this point?

I need tutor help to solve the above question and express your answer using two significant figures.
