2. A uniform ladder 10.0 m long and weighing 50.0 N rests against a smooth vertical wall. (a) If the ladder is just on the verge of slipping when it makes a with the ground, find the coefficient of static friction between the ladder and ground. (b) If the coefficient of static friction is 0.360, and the same ladder makes a angle with respect to the horizontal, how far along the length of the ladder can a 65- kg painter climb before the ladder begins to slip?
