A pitcher throws a 0.75 kg baseball at 30 m/s towards a batter The batter swings and applies 7000N of force on the ball. The contact time between the bat and the ball is 0.0501s.

- Calculate initial momentum of the ball
- Calculate the impulse of the bat on the ball
- Calculate the final momentum of the ball
- Calculate the final velocity of the ball
