A small earthquake starts a lamppost vibrating back and forth. The amplitude of the vibration of the top of the lamppost is 7.0 cm at the moment the quake stops, and 7.6 s later it is 2.0 cm. a. What is the time constant for the damping of the oscillation? b. What was the amplitude of the oscillation 4.0 s after the quake stopped?
