Damped Oscillations

  1. Oct 26, 2006 #1
    A weight of mass m = 300 g hangs vertically from a spring that has a spring constant k = 1.50 N/m. The mass is set into vertical oscillation and after 28 s you find that the amplitude of the oscillation is 1/10 that of the initial amplitude. What is the damping constant b associated with the motion (in kg/s)? Also what would the graphs of the mechanical and kinetic energies look like?

    What is the equation of motion here? Hint: The general form of solution is:

    [tex]x = A_0e^{-qt}\sin(\omega t + \phi)[/tex]
