Homework Answers
a) time period of pendulum
T = 8*0.2 = 1.6 sec
b) frequency , f = 1/T = 1/1.6 = 0.625 Hz
c) amplitude = 6 degrees
d) T = 2*pi*(L/g)^0.5
=> 1.6 = 2*pi*(L/9.8)^0.5
=> length of pendulum , L = 0.632 m

A Review | Constants Part A In a science museum, a 140 kg brass pendulum bob swings at the end of a 14.0 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. At exactly 12:00 noon, how many oscillations will the pendulum have completed? Express your answer as an...
