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