A Uniform Ladder 12 Meters Long Rests Against a Vertical $\theta = 51 ^ { \circ }$

question 8

Short Answer

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 $\theta = 51 ^ { \circ }$ with the floor. A man weighing 874 N climbs slowly up the ladder. When he is 78 m from the bottom of the Iadder, it just starts to slip. What is the coefficient of static friction between the floor and the ladder?
