Deon is running at a velocity of 7.9 meters per second. deon has a total mass of 95 kilograms including his helmet, uniform, pads, and football. if deon runs directly into Chuck , who has a total mass of 120 kilograms and is standing still, what is the momentum of the Deon-Chuck system after the collision

712.5 kg m/s

Explanation:

Work out the total momentum before the event (before the collision):

p = m × v

Massof Deon = 95kg

Velocity =7.5m/s

Mass of Chuck = 120kg

Velocity = 0m/s

Momentum of Deon before = 95 × 7.5 = 712.5 kg m/s

Momentum of Chuck before = 120 × 0 = 0 kg m/s

Total momentum before = 712.5+ 0 = 712.5 kg m/s

Working out the total momentum after the event (after the collision):

Because momentum is conserved, total momentum afterwards = 712.5 kg m/s
