Problem 28E

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. At exactly 12:00 noon, how many oscillations will the pendulum have completed and what is its amplitude?

Solution 28E

Step 1 of 5

The objective here is to determine the number of oscillations completed by a pendulum in a science museum and further, we need to determine its amplitude from the given parameters.
