Question: In a science museum, a 140 kg brass pendulum bob swings at the end of a 14.6 m -long wire. The pendulum is started at exactly 8:00 a.m. every morning by pulling it 1.2 m to the side and releasing it. Because of its compact shape and smooth surface, the pendulum's damping constant is only 0.010kg/s.
At exactly 12:00 noon, how many oscillations will the pendulum have completed?
What is its amplitude at noon?
