A uniform 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 maximum frictional force that the ground can exert on the ladder at its lower end?
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?
