A particle of mass m is driven by a machine that delivers

A particle of mass m is driven by a machine that delivers a constant power of k watts. If the particle starts from rest the force on the particle at time t is

As we know power P =	dw
	dt

⇒ w = Pt =	1	mV²
	2

Hence, acceleration

Therefore, force on the particle at time ‘t’

	1	√mk t^{-1 / 2}
