Q. A damped mass-spring system oscillates at 165 Hz. The time constant of the system is 2.0 s. At t = 0, the amplitude of oscillation is 7.0 cm and the energy of the oscillating system is then 70 J.
(1) What is the amplitude of oscillation at t = 2.00 s?
What is the amplitude at t = 4.00 s?
(2) How much energy is dissipated in the first 2 s interval?
How much energy is dissipated in second 2 s interval?
