What is the instantaneous power of an object resting on a smooth horizontal plane with a mass of M and subjected to a constant horizontal force F. for T seconds

What is the instantaneous power of an object resting on a smooth horizontal plane with a mass of M and subjected to a constant horizontal force F. for T seconds

When momentum equals impulse ft = MV v = ft / m, the instantaneous power of T second is p = FV = FFT / M = ft / m
