Homework Help: Simple Harmonic Question

  1. Jan 7, 2006 #1
    Hello, I was wondering if I am approaching the following problem correctly:

    "A block is on a piston that is moving vertically with simple harmonic motion.
    At what amplitude of motion will the block and the piston separate if the period of the piston is 1.18 s?"

    I am currently doing the following:

    We know F = ma must be less than F= mg. We also know:
    a = acceleration = (2pi x frequency)^2 times A(max amplitude).

    So then we sub 'a' into 'ma < mg' and solve for amplitude A. Is this correct?
