    1. Oops, that was a copy error. The equation for r_{\textrm max} is found on pg. 75 of the text and it is actually given as below.

      r_{\textrm max} = \frac{1}{2\zeta}\sqrt{\sqrt{1+8\zeta^2}-1}

      Notice the plus sign in there. Sorry about that.

    1. I've neglected the weight because of the equilibrium assumption. The problem didn't specifically state that the system begins in equilibrium, but the context of the system told me that it was appropriate. (Consider how often you see a car in a position where its springs are unstretched.)
