Homework Help: Simple Harmonic motion with a compound mass spring system

  1. Apr 26, 2010 #1
    1. The problem statement, all variables and given/known data
    For my problem, I have two springs that have the same length, but different masses and spring constants. Both springs are secured at one end to a holder and at the other ends are connected to a single mass.

    My question is how do I find the angular velocity? Since the equation for angular velocity is...


    My instincts are telling me to just imagine the two springs as one whole spring and combine their mass and spring constant up. Am I on the right track here or would this not be plausable?

    2. Relevant equations

    using the angular velocity formula

    3. The attempt at a solution

    If the two springs are acting in the same direction, then yes, you can combine the two into one "effective spring."

    By the way, that's angular frequency, not angular velocity.

    Thank you for the wisdom and the correction of terminology :D
