Homework Help: The frequency(/time period) of oscillation for a 2 body spring system

  1. Jan 15, 2012 #1
    1. The problem statement, all variables and given/known data

    Two masses m1 and m2 are connected by a spring of spring constant k rest on a frictionless surface. If the masses are pulled apart and let go, the time period of oscillation is :

    I know the answer is T(time period) = 2∏[itex]\sqrt{((m1*m2)/(m1+m2))*1/k}[/itex].
    Can some one help me derive this equation. I know the concept is called reduced mass and think it uses the center of mass as the reference frame.
