A fullback with a mass of 75 kg and a velocity of 4.0 m/s due west collides head-on with a defensive back with a mass of 88 kg and a velocity of 5 m/s due east. (Take the positive direction to be to the west.)
(a) What is the initial momentum of each player? kg·m/s (momentum of full back) kg·m/s (momentum of defensive back)
(b) What is the total momentum of the system before the collision? kg·m/s
(c) If they stick together and external forces can be ignored, what direction will they be traveling immediately after they collide?
