(II) A physical pendulum consists of an 85-cm-long, 240-g-mass,uniform wooden rod hung from a nail near one end (Fig. 14-38).The motion is damped because of friction inthe pivot; the damping force is approximately proportional to d6/dt. The rod is set inoscillation by displacing it 15 from its equilibriumposition and releasing it. After 8.0 s,the amplitude of the oscillation has beenreduced to 5.5. If the angular displacementcan be written as 6 = Ae~yt costo't, find(a) 7, (b) the approximate period of themotion, and (c) how long it takes for theamplitude to be reduced to \ of its original fctS cmvalue.
