Homework Statement
A small earthquake starts a lamppost vibrating back and forth. The amplitude of the vibration of the top of the lamppost is 6.5 cm at the moment the quake stops, and 8.0s later it is 1.8 cm.
What was the time constant for the damping of oscillation?
What's the amplitude of oscillation after 4.0s after the quake stopped?
Homework Equations
A = e^(-t/t)
The Attempt at a Solution
Professor is the worst, she went over the equation but didn't let us know what the variables stand for.
Can someone point me in the right direction? it's probably plug and play, but I won't know since I've never done it or seen it
