When a mass(adsbygoogle = window.adsbygoogle || []).push({}); m, hanging from a string with spring constantk, is set into up-and-down simple harmonic motion, it has a period of vibrationT, which is given by the equation T=2*pi*sqrt(m/k). The amount of elastic potential energy PE stored in the spring at any given instant is dependent on its spring constantkant its elongationx. Determine the potential energy stored in the spring, PE, in terms ofm, T,andx.

I got PE=mgh

m would be the mass in the string and h would be the elongation, but what about acceleration?
