A baseball player swings his 2 kg bat with a speed of 15 m/s. They hit a 0.142 kg baseball which was
approaching at a speed of 40 m/s. the ball rebounds in the other direction at 45 m/s.
If the baseball and bat are in contact for 5 ms, what is the average force the bat exerts on the ball?
How does this compare to the gravitational force on the ball?
