The momentum of an object changes from 20 kg m/s to 5 kg m/s in 3 sec. The value of the applied force will be ______?

The momentum of an object changes from 20 kg m/s to 5 kg m/s in 3 sec. The value of the applied force will be ______?

Explanation

Change in momentum = 20 − 5 = 15 kg·m/s

Time = 3 s → Force = 15 / 3 = 5 N
