A 60 m long 12 kg ladder rests against a smooth vertical, Ask an Expert

Academics

A 6.0 m long, 12 kg ladder rests against a smooth vertical wall with bottom of the ladder 3.0 m from the wall. The coeffecient of static friction between the floor and the ladder is 0.45.

a) What is the force the wall exerts on the ladder?

b) What distance measured along the ladder from the bottom can a 70 kg person climb before the ladder starts to slip.
