"Two football players are moving toward each other in a straight line. Number 56 has a mass of 116 kg and a velocity of 3 m/s (in the positive x direction). Number 22 has a mass of 101 kg and a velocity of 3 m/s (in the negative x-direction). The two players jump into the air and collide perfectly inelastically (they stick together afterwards). Determine the velocity (magnitude and direction) of players, after the collision, before they hit the ground."
