Question: A damped harmonic oscillator loses 5.0 percent of its mechanical energy per cycle.
a) By what percentage does its frequency differ from the natural frequency w = sqr(k/m)?
b) After how may periods will the amplitude have decreased to 1/e of its original value?
What equations do I use? I know the final answers are 8.3 * 10^4 percent and 39 periods. I know that 0.95A is the initial at time T. . .

Energy is directaly proportional to angular velocity,
