Equilibrium: A uniform ladder 12 meters long rests against a vertical frictionless wall, as shown in the figure. The ladder weighs 400 N and makes an angle θ=51∘ with the floor. A mat weighing 874 N climbs slowly up the ladder. When he is 7.8 m from the bottom of the ladder, it just starts to slip. What is the coefficient of static friction between the floor and the ladder?
