PhysicsWork, Energy and PowerJEE Advanced 2013

A particle of mass 0.2 kg is moving in one dimension under a force that delivers a constant power 0.5 W to the particle. If the initial speed (in ) of the particle is zero, the speed (in ) after 5 s is

Answer: 5

Solution

With constant power P, the work done in time t is Pt, which equals the gain in kinetic energy: $Missing argument for \dfrac\dfrac = Pt
