In the pitching motion, a baseball pitcher exerted an average horizontal force of 80 N against the 0.15 kg baseball while moving it through a horizontal displacement of 2.2 m before he released it. How much work did the pitcher do to the baseball as a result of this force? If the baseball’s velocity at the start of the pitching action was zero, how fast was the ball moving at the instant of release?
