Auniform ladder 5.0 m long rests against a frictionless, vertical wall with its lower end 3.0 m from the wall. the ladder weighs 160 n. the coefficient of static friction between the foot of the ladder and the ground is 0.40. a man weighing 740 n climbs slowly up the ladder.
what is the actual frictional force when the man has climbed 1.0 m along the ladder?
how far along the ladder can the man climb before the ladder starts to slip?
