i donno how you guys solved, but i have used normal circuit theory and i got it is v(1-cos(w*t)), so it's peak is 2*v, in fact this is quite common result in transmission lines also.
Oh hell, I did the impulse response, not step response. I now get the same answer as you. I guess chopper and I may have to migrate to management soon before we rust completely.
I guess you could say that all of the energy will slosh back and forth between L and C so the minimum energy in each will be zero at some point in time. So that explains the bottom peak being equal to zero. Furthermore, we could say the midpoint (average value) must be v since the average value of the input must equal the average value of the output given the inductive (DC) coupling (and also the steady state solution with a series resistance that goes to zero will be v). Finally, we know the answer is a sinusoid that must start at zero... It is easy to say such things once you know the answer
