A unifоrm lаdder 12 meters lоng rests аgаinst a vertical frictiоnless wall, as shown in the figure. The ladder weighs 400 N and makes an angle θ = 51° with the floor. A man 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? Show all work.
