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.
Potential Energy: U=(1/2)kx^2
Kinetic Energy: K= (1/2)mv^2
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.
