Suppose that a 112.5 kg football player running at 8.5 m/s catches a 0.44 kg ball moving at a speed of 25 m/s with his feet off the ground, while both of them are moving horizontally. Calculate the change in kinetic energy of the system, in joules, after the player catches the ball. Calculate the change in kinetic energy of the system, in joules, in this case.

Two football players collide head-on in midair while chasing a pass. The first player has a 110 kg mass and an initial velocity of 4.10 m/s in the positive x direction, while the second player has a 125 kg mass and initial velocity of 3.40 m/s in the negative x direction. What is the x component of their velocity just after impact if they cling together? (Indicate the direction with the sign of your answer.)
