Q. Under the action of a constant force, a particle is experiencing a constant acceleration. The power is

Solution:

Instantaneous power is $P=F.v=F$ at
As force and acceleration are constant.
So, velocity of the particle must be keep on increasing
Hence, power is increasing uniformly with time.
i.e. $P \propto t$ .
