1. The problem statement, all variables and given/known data A harmonic oscillator has angular frequency ω and amplitude A. What is the magnitude of the displacement when the elastic potential energy is equal to the kinetic energy? (Assume that U = 0 at equilibrium.) Express your answer in terms of the variables ω and A. 2. Relevant equations Potential Energy: U=(1/2)kx^2 Kinetic Energy: K= (1/2)mv^2 3. The attempt at a solution Honestly, I dont really understand the question. What I was thinking had to be done at first was to set the PE formula equal to the KE formula, and then solve for x, which is the displacement.
