A 0.15 kg baseball is moving at 49 m/s toward home plate when it is hit with the bat. The ball is in contact with the bat for 0.0022 s, and leaves the bat at 25 m/s directly away from home plate. Determine the average force exerted by the bat on the ball.

Answer 1

a = (Vf-Vo)/t = (-25-49)/0.0022 = -33.64
m/s^2.

F = M*a.

Note: The force will be negative, because it opposes the initial motion.
