Transcribed Image Text:
A mass-spring system (mass 0.1 kg) in a medium with a small damping constant is driven at resonance by a sinusoidal force (maximum amplitude Fo). During steady-state motion, the amplitude of oscillation is 0.2 m. When the system reaches x = 0 (equilibrium), its speed is 0.4 ms". (a) What is the value of the spring constant? What is the angular frequency of the driving force? (b) The amplitude of the driving force is now 2Fo. All other parameters are the same as before. At steady state, (c) What is the new amplitude of oscillation? What is the new maximum kinetic energy?
