Homework Help: Find maximum velocity

  1. Oct 29, 2007 #1
    1. The problem statement, all variables and given/known data

    1Kg mass connected to a horizontal spring with a period of 2.25s .
    Find maximum velocity , if amplitude is 6.00cm ?

    2. Relevant equations
    Find K using T= 2pi squroot(m/k)

    3. The attempt at a solution
    Find a from
    F=xK = ma
    is the Velocity = a/t(period)?

    This is a case of simple harmonic motion. We can find the displacement of the mass by using the equation [tex] x = Asin(\omega_0t + \phi) [/tex]. You'll want to find the double derivative of this equation to find the maximum velocity of the mass.

    The velocity is given by the first derivative as usual.
