Two football players are running toward each other. One football player has a mass of 105 kg and is running at 8.6 m/s. The other player has a mass of 90 kg and is running at –9.0 m/s.

The momentum of the system after the football players collide is
kg • m/s.

105 kg and velocity = 8.6 m/s
Momentum = 105*8.6 = 903 kgm/s

90 kg and velocity = -9.0 m/s
Momentum = 90*-9 = -810 kgm/s

Momentum of the system = 903 + (-810) = 903 - 810 = 93
Momentum of the system = 93 kgm/s in the direction of the first football player.
