1. The problem statement, all variables and given/known data Give the following answer in terms of the amplitude, A. At what displacement from equilibrium is the energy of a Simple Harmonic Oscillator two-thirds KE and one-third PE? 2. Relevant equations I would guess PE=.5(k)(x)^2 KE=.5(m)(v)^2 E=.5(k)(x)^2 + .5(m)(v)^2 If one is 2/3, would I change the 1/2 in it's particular equation to 2/3? What would I do from there? 3. The attempt at a solution So far I have no idea where to even begin.
