Part A In the figure, a uniform ladder 12 meters long rests against a vertical frictionless wall. The ladder weighs 400 N and makes an angle 0, of 51 with the floor. A man weighing 638 N climbs slowly up the ladder When he has climbed to a point that is 7.8 m from the base of the ladder, the ladder starts to slip. What is the coefficient of static friction between the floor and the ladder? 7.8 m Express your answer using two significant figures The ladder is placed against a vertical wall, and its lower end is resting on a horizontal floor. The ladder makes angle theta with the floor. A man is AEd standing on the ladder at a distance of 7.8 meters from its base.
