A 0.15 kg baseball collides with a 1.2 kg bat. The ball has a velocity of 43 m/s immediately before the collision. The center of mass of the bat has a velocity of 45 m/s in the opposite direction of the ball. The coefficient of restitution between the bat and the ball is 0.54. Estimate how fast the baseball is moving as it leaves the bat following the collision.
