Problem 11.81 - Enhanced - with Feedback A garage door is mounted on an overhead rail (Figure 1). The wheels at A and B have rusted so that they do not roll, but rather slide along the track. The coefficient of kinetic friction is 0.55. The distance between the wheels is 2.00 m, and each is 0.50 m from the vertical sides of the door. The door is uniform and weighs 850 N. It is pushed to the left at constant speed by a horizontal force F, that is applied as shown in the figure. Figure A 2.00 m- k3.00 m B h 1 of 1 F Part A If the distance h is 1.60 m, what is the vertical component of the force exerted on the wheel A by the track Express your answer to two significant figures and include the appropriate units.
