Spring and equilibrium problem

  1. Feb 23, 2009 #1
    1. The problem statement, all variables and given/known data

    A 0.340kg- mass is attached to a spring with a force constant of 13.0 N/m.
    If the mass is displaced 0.250m from equilibrium and released, what is its speed when it is 0.140m from equilibrium?
    in m/s
    for some reason cannot get the correct answer.

    omega=square roote of k\m
    T=1.47
    k=13.0
    not sure of amplitude
    eqn v=-Aomega*sin(omegat)

    answers were like 0.87 m/s 0.5981m/s
    1.54m\s
    i cannot seem to get it correct

    Why don't you use energy conservation.
