A ladder having a uniform density and a mass m restsagainst a frictionless vertical wall, making angle 48.0° with thehorizontal. The lower end rests on a flat surface where thecoefficient of static friction is µs = 0.370. A windowcleaner with mass M = 2m attempts to climb theladder. Given a ladder length of L, what fraction of thelength of the ladder (x / L) will the worker have reachedwhen the ladder begins to slip?
