Energy in SHM

  1. Oct 18, 2006 #1
    Hi some help on the following problem would be very useful.

    The probem is based around a mass with two horizontal springs attached to it, one on either side.

    "A mass m = 1 kg is mounted between two identical springs of K = 100 N/cm"

    What is the portential energy of either spring if the mass is in position z? What is the kinetic energy of the mass? and what is the total enery Et"

    Any help would be appreciated.

    Regards, William.

    What is position z? Can you describe it or post a drawing?

    Well z is actually equal to the extension of the spring. Other than that there is no drawing.

    z is the extension of one spring? or both? What is the extension of the other spring if they are not the same.
