Express your answer in meters per second squared part B) At the lowest point of the circle, the ball has reached its maximum speed. What is the magnitude of the...
on 29 of 31> 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 29.4 m/s (about 65.8 mph). Just before the ball leaves her hand, the ball's radial acceleration is 4230 m/s. What is the length of her arm from the pivot point at her shoulder? length TOOLS
need answer for part B please! A tennis player swings her 1000 g racket with a speed of 12 m/s. She hits a 60 g tennis ball that was approaching her at a speed of 16 m/s. The ball rebounds at 36 m/s. Part A How fast is her racket moving immediately after the impact? You can ignore the interaction of the racket with her hand for the brief duration of the collision. Express your answer using two significant figures....
