1. A uniform coin with radius R is pivoted at a point that is a distance d from its center. The coin is free to swing back and forth in the vertical plane defined by the plane of the coin. For what value of d is the frequency of small oscillations largest?

2. V(x)$$\equiv$$potential energy; V(x)$$\approx$$$$\frac{1}{2}$$V"(x$$_{o}$$)(x-x$$_{o}$$)$$^{2}$$ ; omega is equal to the square root of V"(x)/m

3. I have no idea what to do. My textbook is vague and my notes from lecture are not sufficient. I don't want a solution, just a push in the right direction

Treat this as a physical pendulum. Begin by finding the moment of inertia about the pivot.
