During a big game, a 68 kg football player initially at rest catches a punt on a completely firctionless horizontal surface. The football has a mass of 0.43 kg and is moving at a speed of 27 m/s at a 59 degree angle below horizontal. What is the speed of the football player with the football after the catch?
