The answer is 40 m/s but I don't get how to do it. During the pitching motion, a baseball pitcher exerts an average horizontal force of 60 N against the .15 kg baseball while moving it through a horizontal displacement of 2.0 m before he releases it. If the baseball player's velocity is zero, how fast was the ball moving at the instant of release?
