A particle of mass 2 kg starts moving in a straight line with an initial velocity of

2\mathrm{\;m}{\mathrm{s}^{ - 1}}

at a constant acceleration of

2\mathrm{\;m}{\mathrm{s}^{ - 2}}

. Then rate of change of kinetic energy

View answer and explanation

Correct option: A

Is four times the velocity at any moment

Option A (Is four times the velocity at any moment) is correct because the rate of change of kinetic energy is equal to the power, which is force times velocity, and the force is related to the acceleration.
