A small earthquake starts a lamppost vibrating back and forth. The amplitude of vibration of the top of the lampost is 6.0cm at the moment the quake stops, and 7.8s later it is 2.2cm.

Part A: What is the time constant for the dampening of the oscillation?

Part B: What was the amplitude of the oscillation 3.9s after the quake stopped?
