In Fig. 15-46, a stick of length L = 1.8 m oscillates as a physical pendulum. (a) What value of distance x between the stick's center of mass and its pivot point O gives the least period? (b) What is that least period?(adsbygoogle = window.adsbygoogle || []).push({});

For this problem, I wasn't sure where to start, I would have thought that the answer would be as far away from the center of mass as possible but I wasn't sure how to do it. I know that you have to use the equation Period = 2 x pi x (square root of (Icom/m x g x h) and that mass cancels out, but I don't know where to go from there, thank you in advance for the help
