The pendulum in a grandfather clock has a period of 1.00 sec? If the clock's driving spring is allowed to run down, damping due to the friction will cause the pendulum to slow to an eventual stop. If the time constant for decay is 300 sec, how long will it take for the pendulum's swing to be reduced to half its initial amplitude?
