A small earthquake starts a lamppost vibrating back and forth. The amplitude of the vibration of the top of the lamppost is 6.4cm at the moment the quake stops, and 7.8s later it is 1.4cm .

a) What is the time constant for the damping of the oscillation?

b) What was the amplitude of the oscillation 3.9s after the quake stopped?
