Homework Help: Damped Oscillator and amplitude

  1. Jan 16, 2012 #1
    1. The problem statement, all variables and given/known data[/b]
    Consider the damped oscillator illustrated in the figure below. Assume that the mass is 365g, the spring constant is 112N/m, and b = 0.117kg/s. How long does it take for the amplitude to drop to half its initial value? (A*e-b*t/(2m))


    2. Relevant equations

    3. The attempt at a solution

    I solved for ω using the two of the above equations and got 17.5 rad/s
    i just don't know where to go from here, any suggestions ?
