A rotating door is made from four rectangular glass panes. The mass of each pane is 90kg. A person pushes on the outer edge of one pane with a force of F=70N that is directed perpendicular to the pane. Determine the magnitude of the door's angular acceleration. in rad/s2

I will be happy to critique your work on this. The key is modeling the door so that you can get the moment of inertia.
