    Energy of an damped/undriven oscillator in terms of time?

    i can't seem to get it in the form dE/dt=-bV^2.

    Energy of an damped/undriven oscillator in terms of time?

    Homework Statement The Q asks to show that the time rate of change in mechanical energy for a damped, undriven oscillator is dE/dt=-bV^2.Homework Equations I assume you take the derivative of the total E eq, E=(1/2)mV^2 + (1/2)kx^2 but I'm unsure how to put the E eq into terms of t, like...
