  1. An object of mass, m = 0.200kg, is hung from a single spring with spring constant,

      k = 80.0N/m. (Ignore the mass of the spring.) The object is subject to a resistive force, f,

      given by f =-bv where v = the velocity of the mass in m/s.   

  1. If the damped frequency, w’ = 0.75w0, the undamped frequency, what is the value of “b”?
  2. What is the “Q” of the system?
  3. By what factor is the amplitude of the oscillation reduced after 10 complete cycles?
