Power

A particle of mass M, starting from rest, undergoes uniform acceleration. If the speed acquired in time T is V, the power delivered to the particle is

Show answer and solution

Answer: (d)

Work done $= \Delta KE = \dfrac{1}{2}MV^2$ .
Average power $P = \dfrac{W}{T} = \dfrac{MV^2}{2T}$
So the answer is (d).
