Question

- 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 =-b**v**
where v = the velocity of the mass in m/s.

- If the damped frequency, w
*’*= 0.75w_{0}, the undamped frequency, what is the value of “b”? - What is the “Q” of the system?
- By what factor is the amplitude of the oscillation reduced after 10 complete cycles?
