The base of a damped spring-mass system, with m=25 kg and k = 2500 N/m, is subjected to a harmonic excitation y(t) = Y cos wt. The amplitude of the mass displacement is found to be 0.05 m when the base is excited at the natural frequency of the system with Y=0.01 m. Determine the damping constant of the system.
