Question:
A uniform ladder, of length 2a and mass in, is resting against a smooth vertical wall and a rough horizontal floor. The ladder is making an angle of 30° with the wall, and the coefficient of friction between the ladder and the floor 1/2√3. An electrician, of mass 8m, is trying to ascend the ladder. Determine how far they can walk up the ladder before it slips.
