A damped mass-spring system oscillates at 190 Hz. The time constant of the system is 2.0 s. At t = 0, the amplitude of oscillation is 6.5 cm and the energy of the oscillating system is then 65 J.
(a) What is the amplitude of oscillation at t = 2.0 s?
What is the amplitude at t = 4.0 s?
(b) How much energy is dissipated in the first 2 s interval?
How much energy is dissipated in the second 2 s interval?
