A 120 kg football player is running at 8.15 m/s A hand-thrown 0-410 kg football has a speed of 275 m/s. (Assume the football player is running in + y-direction).  Assuming that the football player catches the ball with his feet off the ground with both of them moving horizontally, calculate the following:

 (a) the final velocity (in m/s) if the ball and player are going in the same direction (Indicate the direction with the sign of your answer).

(b) the loss of kinetic energy (in) J.

(c) Repeat parts (a) and (b) for the situation in which the ball and bat are going in opposite direction.(indicate direction with sign).
