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! :)
