Suppose a fast-pitch softball player does a windmill pitch, moving her hand through a circular arc with her arm straight. She releases the ball at a speed of 26.4 m/s (about 59.1 mph). Just before the ball leaves her hand, the ball's radial acceleration is 290 m/s2. What is the length of her arm from the pivot point at her shoulder?
