Question

A baseball pitcher can throw a baseball at a velocity of 44.9 m/s. If the mass of the ball is 0.17 kg and the pitcher has it in his hand over a distance of 2.18 m, what is the average force exerted by the pitcher on the ball?

Answer 1

Work = Force x distance = the change in kinetic energy
\[Fd = \frac{1}{2}mv_2^2\]
because \[v_1 = 0\]

Answer 2
