Simple Harmonic Motion - At which rate will a ball vibrate

  1. Apr 25, 2010 #1
    A hanging wire is 1.80 m long. When a 60.0 kg ball is suspended from the wire, the wire stretches 2.00 mm. If the ball is pulled down a small additional distance and released, at what frequency will it vibrate? Assume that the stress on the wire is less than the proportional limit.
    I have found an answer but it seems too simple and does not take into account the length of the wire but im pretty sure that it should. any help is appreciated. thanks


    2. Relevant equations

    F=kx
    T=2pi*sqrt(m/k)
    f=1/T

    3. The attempt at a solution
    Found the spring constant to be 294300n/m

    then found the period of oscillation to be 0.0897s
    then inverted it to find the frequency to be 11.15hz
