Consider the collision between two football players (a tackle and a guard). The tackle has a mass of 82kg and achieves a velocity of +2.5 m/s after the snap. The guard has a mass of 85 kg and achieves a velocity is -2.3 m/s after the snap. This will be the total momentum of the players [including direction] after colliding.
What is +9.5 kg m/s in the direction of the tackle?
