Q. A damped mass-spring system oscillates at 275-Hz. The time constant of the system is 2.0 s. At t = 0, the amplitude of oscillation is 3.20cm and the energy of the oscillating system is then 32 J.
(i) What is the amplitude of oscillation at t = 2s?
What is the amplitude at t = 4.0s?
(ii) How much energy is dissipated in the first 2 s interval?
How much energy is dissipated in second 2 s interval?
