Homework Help: SHM and Angular Frequency

  1. Feb 4, 2009 #1
    1. The problem statement, all variables and given/known data
    If provided only the spring constant K and the mass of an object undergoing simple harmonic motion how do you find the amplitude?

    2. Relevant equations
    Angular Frequency = sqrt (k/m)
    Period = 1/t

    3. The attempt at a solution
    Using the two equations above you can derive [tex]\omega[/tex] period, and frequency. This gives you [tex]\omega[/tex], period, frequency, mass and the spring constant. Is it possible to solve for the amplitude with these variables?

    Amplitude is a function of the energy in the SHM system and we don't have any information about that.

    TotalEnergy = 0.5*K*Amplitude²
