1. The problem statement, all variables and given/known data A rotating door is made from four rectangular glass panes, as shown in the drawing. The mass of each pane is 90 kg. A person pushes on the outer edge of one pane with a force of F = 80 N that is directed perpendicular to the pane. Determine the magnitude of the door's angular acceleration.________rad/sec squared. (there is a pic that shows radius 1.2m) 2. Relevant equations net external torque=moment of inertia x angular acceleration 3. The attempt at a solution Tried (90kg*4 panes*1.2m squared) to get moment of inertia=518.40. Then divided 80N b by 518.40 to solve for angular accel=.1543 This isn't right. Will anyone help?
