Harmonic Motion

  1. Nov 13, 2008 #1
    1. The problem statement, all variables and given/known data
    A 0.296 kg mass is attached to a spring and executes simple harmonic motion with a period of 0.18 s. The total energy of the system is 3.3 J. Find the force constant of the spring. Answer in units of N/m.

    2. Relevant equations

    3. The attempt at a solution
    I get 0.0002429276699 but it is wrong. Any ideas what i did wrong?

    Your equation is wrong. The period should be T = 2pi times the square root of (m/k). I believe that your equation has (k/m) instead of (m/k). Hope that helps.

    Note also: you should learn the trick of carrying through your units and checking them... that would have helped you find this error.
