1. In the figure below, a book is suspended at one corner so that it can swing like a pendulum parallel to its plane. The edge lengths along the book face are 28 cm and 19 cm. If the angle through which it swings is only a few degrees, what is the period of the motion? 2. I=(ML^2)/12 I=(ML^2)/3 T=2∏√I/M*G*dcom 3. I got dcom by using the distance formula and it's .1692 m Then I tried to using both inertia equations and using length, width. Then I plugged in all the numbers. (multiple attempts) All wrong answers (.788s, .394s, 1.062s) Appreciate your help! :) .
