can you help me with this, please?
Firstly it doesn't say "one second" it says "per second" which is a rate.
Momentum = mass * velocity
Momentum per second would be equal to mass * velocity / time
Velocity/time = acceleration.
can you do the rest?
Force is the change in momentum per unit time.
F=ma (m=mass a=acceleration)
Replacing a into the force equation:
Which is change in momentum per unit time.
thanks a lot NihalRi @CWatters :
