A rope of length L = 2m and mass m = 2.2 kg is initially at rest and can slide on an inclined surface with incline 8 = 25° as shown in the figure. Assume that the part of the rope that is not on the inclined surface hangs down vertically at all times and that the static friction coefficient between the rope and the surface is μ, = 0.63.

A uniform ladder with mass m₂ = 14kg and length L = 3.2m rests against a smooth wall. A do-it-yourself enthusiast of mass m₁ = 70kg stands on the ladder a distance d = 1.2m from the bottom (measured along the ladder.) There is no friction between the wall and the ladder, but there is a frictional force, with μ = 0.25, between the floor and the ladder. N₁ is the magnitude of the normal force exerted by the wall on the ladder, and N₂ is the magnitude of the normal force exerted by the ground on the ladder.
