2. A uniform ladder 10.0 m long and weighing 50.0 N rests against a smooth verticalwall. (a) If the ladder is just on the verge of slipping when it makes a 50.0°with the ground, find the coefficient of static friction between the ladder andground. (b) If the coefficient of static friction is 0.360, and the same laddermakes a 60.0° angle with respect to the horizontal, how far along the length ofthe ladder can a 65-kg painter climb before the ladder begins to slip?
