A uniform ladder 5.30 m long rests against a frictionless, vertical wall with its lower end 3.10 m from the wall. The ladder weighs 157 N . The coefficient of static friction between the foot of the ladder and the ground is 0.430. A painter weighing 739 N climbs slowly up the ladder.
How far along the ladder can the painter climb before the ladder starts to slip?
