The velocity of a body of mass increases from to when a force acts on it for . What is the gain in momentum per second?
Step 1: Given Data:
Mass,
Initial velocity,
Final velocity,
Step 2: Formula used: Gain in momentum,, where and are final and initial velocity respectively.
Step 3: Calculation of gain in momentum:
Gain in momentum for 2 s,
Gain in momentum per second,
