Also, the center ofmass is a distance, L, from the axis ofrotation. If the object swings in gravityfrom the axis of rotation, what is theequation of motion, θ (t)?Physics 207: Lecture 26, Pg 12Example: The Physical PendulumExample: The Physical PendulumSuppose the pendulum is a string of L = 1m.At t = 0 the pendulum is at θ = 0 and has aninitial angular velocity of + 1 radian/second.What is θ (t)?Physics 207: Lecture 26, Pg 16Physics 207: Lecture 26, Pg 17Standing Wave ExampleStanding Wave ExampleThe lowest note on a large pipe organ is16.4 Hz. (This extreme base note, 4octaves below middle C, is more felt asa rumble than heard with the ears.)What is the length of the
