Homework Help: Energy in Simple Harmonic Motion

  1. Dec 6, 2007 #1
    A 1.3 kg object oscillates with simple harmonic motion on a spring of force constant 410.0 N/m. The maximum speed is 0.7 m/s. What is the total energy of the object and the spring?

    Do I just set it up like this:

    1/2*410*x^2=1/2*1.3*.7^2 to get the max x
    Then do I just add them up

    No. Both are equal to the total energy. Use just one of them.

    Easier would be to write E_tot = (1/2)m(v_max)^2, since m and v_max is given.
