a mass-spring-damper system has a mass of 100 kg. In 60 s, its free response apmplitude decays such that the amplitude of the 30th cycle is 20% of the amplitude of the 1st cycle. Estimate the damping constant c and the spring constant k.
A mass-spring system is driven by the external force g(t) = 2 sin3t + 10 cos 3t. The mass equals 1, the spring constant equals 5, and the damping coefficient equals 2. If the mass is initially located at y (0) =-1, with initial velocity y' (0) = 5, find its equation of motion to find y (1). Round up the answer to the second decimal place point.

A damped single degree of freedom mass-spring system is excited at resonance by a harmonic forcing function which has an amplitude of 80 N. It was observed that the steady state amplitude of the forced vibration is 6 mm. It was also observed that when the frequency of excitation is three times the natural fre- quency of the system, the amplitude of the steady state vibration becomes 1 mm.
