A panicular spring has a spring constant of 86 N/m and a mass of 0.548 kg at its end. When the spring is driven in a viscous medium, the resonant motion occurs at an angular frequency of 12.2 rad/s. What is
(a) the damping parameter due to the viscous medium?
(b) the lifetime of the system?
(c) the sharpness of the resonance peak?
