A uniform ladder 5.0 m long rests against a frictionless,vertical wall with its lower end 3.0 m from the wall. The ladderweighs 160 N. The coefficient of static friction between the footof the ladder and the ground is 0.40. A man weighing 740 N climbsslowly up the ladder.

a) What is the maximum frictional force that the ground canexert on the ladder at its lower end?

b) What is the actual frictional force when the man hasclimbed 1.0 m along the ladder?

c) How far along the ladder can the man climb before theladder starts to slip?
