Help plsss A uniform ladder rests against a frictionless wall at an angle of -46.0° with respect to the ground. If the weight of the ladder is W-280 N, the length is L-7.5m, and the coefficient of static friction between the ladder and the ground is μs-0.75 determine the distance a man with a weight of WM-825 N can climb along the ladder before the ladder begins to slip. 8.77 since the ladder is in equilibrium up to the instant...
A uniform ladder of length L and weight w is leaning against a vertical wall. The coefficient of static friction between the ladder and the floor is the same as that between the ladder and the wall. If this coefficient of static friction is μs = 0.585, determine the smallest angle the ladder can make with the floor without slipping.
