Homework Help: Forced Mass on Spring please help

  1. Nov 29, 2006 #1
    1. The problem statement, all variables and given/known data

    A mass of 2kg is hung on a spring of spring constant 3.92 x 103 Nm-1. The natural frequency for the system is wo = 44.3 s-1. The system is forced to vibrate by an alternating force of amplitude
    F = 2 cos (wt) Newtons.
    What is the amplitude of vibration when w = 20 s-1

    2. Relevant equations

    3. The attempt at a solution
