During the pitching motion a baseball pitcher exerted an, Ask an Expert

Academics

During the pitching motion, a baseball pitcher exerted an average horizontal force of 60 N against the 0.15 kg baseball while moving it through a horizontal displacement of 2.0 m before he released it.

How much work did the pitcher do to the baseball as a result of this force?

Was the work done positive or negative?

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?
