Painter on a ladder (This problem will be graded base upon your scanned handwritten solution) Consider a ladder with a painter climbing up it. The mass of the uniform ladder is 17.0 kg, and the mass of the painter is 77.0 kg. If the ladder begins to slip at its base when the painter's feet are 57% of the way up the length of the ladder, what is the coefficient of static friction between the ladder and the floor? Assume the wall is frictionless. FW FCy 4.0 m mg IMg FCx 3.0 ml- - 2.1 m
