Compute there given question:
Question: In a science museum, a 100kg brass pendulum bob swings at the end of a 16.9m -long wire. The pendulum is started at exactly 8:00 a.m. every morning by pulling it 1.6m to the side and releasing it. Because of its compact shape and smooth surface, the pendulum's damping constant is only 0.010kg/s.
Question I: At exactly 12:00 noon, how many oscillations will the pendulum have completed?
Question II: And what is its amplitude?
Show all work and steps, use additional paper if necessary. Thank you.
