Question) A ladder of length 3.0m and mass 40.0kg leans against a wall such that it makes an angle of 60.0◦ with the horizontal. There is friction between the ladder and the floor (μs= 0.25), but there is no friction between the ladder and the wall.A person of mass 71 kg climbs the ladder.

1) How far up can the person climb before the ladder will slip?

2) When the person is at the point found in (1), what is the net force from the floor on the ladder?

3) If the person had wanted to safely climb the ladder higher than what you found in (1), what should they do? Explain your reasoning.

A 5.5 m long ladder with a mass of 10.0 kg is leaning against a wall at a dangerously large angle of 35° (between the ladder and the wall). The coefficient of static friction between the base of the ladder and the floor is 0.50 and the top of the ladder has wheels so there is negligible friction between the ladder and the wall.

Romeo takes a uniform 11.5-m ladder and leans it against the smooth wall of the Capulet residence. The ladder's mass is 24.0kg, and the bottom rests on the ground 2.80m from the wall. When Romeo, whose mass is 70 kg, gets 87.0 percent of the way to the top, the ladder begins to slip. What is the coefficient of static friction between the ground and the ladder?
