Suppose that a 95 kg football player running at 8.5 m/s catches a 0.49 kg ball moving at a speed of 25 m/s with his feet off the ground, while both of them are moving horizontally.

a) Calculate the velocity of the football player and the ball after the catch.
b) Determine the change in momentum of the system.
c) Find the impulse exerted on the football player during the catch.
