In the figure below, a damped simple harmonic oscillator has mass m = 220 g, k = 95 N/m, and b = 70 g/s. Assume all other components have negligible mass. What is the ratio of the amplitude of the damped oscillations to the initial amplitude at the end of 20 cycles (Adamped / Ainitial)?

I will be happy to critique your thinking.

This is impossible to answer this way, since the initial amplitude isn't given.
