A damped mass-spring oscillator loses 8% of its energy during each cycle. The period is 7.7 s, and the mass is 0.9 kg. (Assume the equation describing the amplitude of the oscillator is A (t) = Aoe'bwm) (a) What is the value of the damping constant? kg/s (b) If the motion is started with an initial amplitude of 0.37 m, how many cycles elapse before the amplitude reduces to 0.14 In
