Question

Please Solve 2 physics problems for me...

1. a 79.9 kg football player moving with a speed of 4.68m/s collides mid-air with another player and gets knocked backwards. if the player experiences an average force of 2560N over a time period of 0.234s, then determine the speed (in m/s) of the player.

2. A 0.144kg softball is pitched horizontally at 32m/s. The ball moves in the opposite direction at 32.0m/s after it is hit by the bat.

a) what is the change in momentum of the ball?

b) what is the impulse delivered by the bat?

c) If the bat and softball were in contact for 0.8ms, what is the average force that the bat exerted on the ball?

thank you so much
