Harmonic Motion-Just need to make sure

  1. Nov 18, 2007 #1
    1. The problem statement, all variables and given/known data
    A mass of 100 g is hanging from a spring and is set into simple harmonic motion. If the period of the pendulum is 0.993 s, what is the spring constant?



    2. Relevant equations

    T=2pi(m/k)1/2

    3. The attempt at a solution
    I just want to make sure its right before I plug in the answer. Thanks.

    T^2 = 2pi *(m/k)

    k*T^2 = 2pi * m

    k = (2pi*m)/T^2 = .637 N

    T^2 = 2pi *(m/k)

    T^2 = 4(pi)^2*(m/k)
