Answer :

Momentum = Mass [tex]\times[/tex] Velocity
                 = 60kg [tex]\times[/tex] 9m/s
                 = 540kg m/s

The momentum of a 60-kg halfback is 540 kg m/s.

What is momentum?

Momentum is product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction.

Momentum = Mass * Velocity

                    = 60kg*9m/s

                    = 540kg m/s
