The weight W = 5 lb, the spring constant is k = 5 lb/ft, and the damping constant is c = 0.55 lb-s/fl The spring is unstretched when x = 0. The mass is displaced to the position x = 3 ft and released from rest. (a) What is the natural frequency and damping of the system? (b) If the damping is subcritical what is the frequency of the resulting damped vibrations?
