A circular disk with a rectangular hole has a radius of 0.500 m and mass of 0.300 kg. It is suspended by a point on its perimeter as shown in the figure. The moment of inertia about this point is I_p = 4.80E-1 kgm2. Its center of mass is located at a distance of s=0.120 m from the center of the circle as shown. If the disk is allowed to oscillate side to side as a pendulum, what is the period of oscillations?
