    I answered this a few days ago and apparently something went wrong with the transmission.

    To paraphrase, your understanding of power is incorrect.
    Power is NOT A^2/2.
    If A is voltage, Vsinwt ...

    Wrong, as the Q gets larger the amplitude and the velocity get larger in the same proportion.
    What you need to do is write the ODE and solve it for the harmonic input. The input power is F*x', but...

    Explain exactly what the system is and where you get an output energy.
    Also in the system you describe , for example anLRC circuit,where w=wn, the current is in phase with the voltage.
    For the...
