To solve this problem, please read the section 15.6 on the textbook that deals with the pendulum as an oscillator. Feel free to consult the textbook for this problem. 1. A physical pendulum consists of a thin homogeneous rod of length L, suspended by a point O at a distance x from the center of gravity. Recall I = -ml2 for a rod 1/2 12 like this rotating about its center of mass. O a. Assume that x = L/2, i.e., the point O is at the end of the rod. Find the frequency and period of oscillation of the pendulum. b. Write an expression for 0(t) (the angle the pendulum makes with the vertical at a time t) for the situation in part a and assuming that at t = 0, 0 is maximum and is equal to 10. 1/2 c. When x is allowed to change, find the frequency and period of oscillation as a function of x. Assume x
