A fastpitch softball player does a "windmill" pitch moving her hand through a vertical circular arc to pitch a ball at 68mph. The 0.19 kg ball is 55 cm from the pivot point at her shoulder.
a. Just before the ball leaves her hand, what is its centripetal acceleration?
b. At the lowest point of the circle, the ball has reached its maximum speed. What is the magnitude and direction of the force her hand exerts on the ball at this point?
