Homework Help: Harmonic Motion

  1. May 2, 2005 #1
    For some reason this problem has me stuck. It isn't homework, but it might be on the exam Tommorrow. If anyone is still awake, please steer me in the right direction. Thank you

    A simple harmonic oscillator has a total energy of E.
    (a) determine the kinetic and potential energies when the displacement is one half the amplitude. (b) For what value of the displacement does the kinetic energy equal the potential energy....

    When the displacement is the amplitude, all the energy is potential energy. How does the potential energy depend on the displacement? The formula is ?????

    When potential and kinetic energy are equal, each is half of the total, so just find where the potential energy is half of maximum.
