A pitcher accelerates a 0.14-kg hardball fromrest to 42.5 m>s in 0.060 s. (a) How much work does the pitcherdo on the ball? (b) What is the pitcher’s power output during thepitch? (c) Suppose the ball reaches 42.5 m>s in less than 0.060 s.Is the power produced by the pitcher in this case more than, lessthan, or the same as the power found in part (b)? Explain
