For the next three problems, in a science museum, a 110-kg brass pendulum bob swings at the end of a 15.0-m-long wire. The pendulum is started at exactly 8:00 a.m. every morning by pulling it 1.5 m to the side and releasing it. Because of its compact shape and smooth surface, the pendulum's damping constant is only 0.010 kg/s. 19. At exactly 12:00 noon, how many oscillations will the pendulum have completed? (Answer: N = 1853) 20. What is its amplitude? (Answer: A = 0.78 m) 21. How much energy has been dissipated by 12:00 noon? (57.4 J)
