Question:
A physics department has a Foucault pendulum, a longperiod pendulum suspended from the ceiling. The pendulum has an electric circuit that keeps it oscillating with a constant amplitude. When the circuit is turned off, the oscillation amplitude decreases by \(50 \%\) in 22 minutes. What is the pendulum's time constant? How much additional time elapses before the amplitude decreases to \(25 \%\) of its initial value?
