A damped mass-spring system oscillates at 113 Hz. The time constant of system is around 9.5 s. At t = 0 the amplitude of oscillation is 5 cm and the energy of oscillating system is around 86 J.
i) Determine the amplitude of oscillation at t = 0.2 s?
ii) Determine how much energy is dissipated in the first period (.2 s interval)?
iii) Determine how much energy is dissipated in the second period (.2 s interval)?
