Homework Help: Simple Harmonic Motion Maxiumum Velocity

  1. May 19, 2008 #1
    Hi, wondering if someone could help me with the following question.

    A mass is hung from the lower end of a light vertical spring, whose upper end is fixed. The mass is pulled down and released and the time period of the oscillating system is measured. If the time period is 0.25s and the amplitude of oscillation is 30mm, calculate:

    i.)the maximum speed
    ii.)the maxiumum acceleration

    I have an equation for the speed:

    ds/dt = A 2(pi)f cos(2(Pi)ft)

    i have a value for the frequency, is the maximum speed when the value of cos(2(Pi)ft) = 1?
