Homework Help: 2009 f=ma #24

  1. Jan 31, 2012 #1
    1. The problem statement, all variables and given/known data
    Two identical objects of mass m are placed at either end of a spring of spring constant k and the whole system is placed on a horizontal frictionless surface. At what angular frequency ω does the system oscillate?


    2. Relevant equations
    ω=√(k/m)


    3. The attempt at a solution

    Total mass is 2m, so ω=√(k/2m)

    Apparently that's not right, though my answer does not really seem reasonable, as it should be oscillating faster than with one mass...?
