Can someone check my work please I'm pretty sure I don't have the right answer but I can't figure out what I have wrong. The question is: A simple harmonic oscillator has total energy E=1/2kA^2 where A is the amplitude of oscillation. For what value of the displacement does the kinetic energy equal the potential energy? So I figure that if KE is equal to PE, then PE=1/2E Therefore: 1/2kx^2 =1/2(1/2kA^2) kx^2 = 1/2kA^2 x = 1/4A Any ideas?
