Homework Help: Please help with this Harmonic Motion

  1. Nov 6, 2005 #1
    Please help with this!! Harmonic Motion

    Two masses m1=100 g and m2=100 g slide freely in a horizontal frictionless track and are connected by a spring whose force constant is k=.5 N/m. Find the frequency of oscillatory motion for this system. I know omega = sqrt (k/m), but I have two masses, rather than just one. How does this work? Could someone give me an idea of how I should go about solving this?

    there's a place in the spring which doesn't move (the center-of-mass).
    so each side of the spring stretches independently, with a new k.
