What are the units for momentum?

anonymous · Answer

The equation for momentum is p = mv. The units for momentum are kilogram-meters per second (kg·m/s).

Hi so impulse is the connection between time and change in momentum,
Force= Mass x Acceleration
Momentum= Mass x Velocity
Acceleration= Change in velocity/ time
therefore Force= Mass x Change in velocity/time.
So the average force times time exerted = impulse. the average for is 10,000/5 which is 2000 times time which is 5, so the answer is 10,000 kgm/s!
