    Question Related Rates: Kinetic Energy

    The kinetic energy of an object is K=v^2 when its mass is 2 kg, where v is the speed(in m/s). Suppose such an object is travelling at 4 m/s and is experiencing an acceleration of 3 m/s/s. Determine the rate of change in its kinetic energy.

    check your formula ...

    K = \frac{1}{2}mv^2

    \frac{d}{dt}\left[K = \frac{1}{2}mv^2\right]

    \frac{dK}{dt} = mv \cdot \frac{dv}{dt}
