in a science museum, a 110kg brass pendulum bob swings at the end of a 13.2m -long wire. The pendulum is started at exactly 8:00 a.m. every morning by pulling it 1.7m to the side and releasing it. Because of its compact shape and smooth surface, the pendulum's damping constant is only 0.010\;{\rm kg/s}. At exactly 12:00 noon, how many oscillations will the pendulum have completed? And what is its amplitude?
