Driven, damped oscillator - !

    Driven, damped oscillator - URGENT!

    1. The problem statement, all variables and given/known data
    A driven, undamped oscillator has an amplitude of 3.0cm at a driving frequency of 9 rad/s and an amplitude of 2.4cm at a driving frequency of 7 rad/s. What is the resonant frequency of the oscillator?

    2. Relevant equations
    A = (F0/m)/(w0^2-w^2)

    3. The attempt at a solution
    My prof. gave me the above formula as a hint, but I have no idea where to start from and what to do. Thanks for the help!

    The resonant frequency is [tex]\omega_0[/tex]. It looks like you have two formulas, and two unknowns: [tex]F_0 / m[/tex] and [tex]\omega_0[/tex]. Should be solveable.
