Question
A body moves under a force such that momentum of body at any instant is,
What is the rate of work done by the force?
Solution
Since the momentum of the body at any instant is given by,
∴ Force is given by,
We know, the rate of work done is power P which is given by,

∴ Rate of work done is zero.
∴ Force is given by,
We know, the rate of work done is power P which is given by,
∴ Rate of work done is zero.
