Homework Help: Simple Harmonic Motion - position

  1. Apr 30, 2010 #1
    1. The problem statement, all variables and given/known data

    A 100 g ball attached to a spring with spring constant 2.9 oscillates horizontally on a frictionless table. Its velocity is 20 cm/s when x = 4.8 cm.

    What is the ball's maximum acceleration?
    which I found to be amax= 180 cm/s^2

    What is the ball's position when the acceleration is maximum?

    2. Relevant equations

    x(t)= Acos(ωt)
    x(t)= Acos(2pift)
