HERE IS THE ANSWER
Explanation:
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.

Answer:
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.
