If the coefficient of static friction is 0.55, and the same ladder makes a 48 angle with respect to the horizontal, how far along the length of the ladder can a 59.0-kg person climb before the ladder begins to slip? The ladder is 7.5 m in length and has a mass of 21 kg. 6.34 X Use the equations that result from applying the conditions for the system to be in equilibrium with the friction force given by the coefficient of maximum static friction. m
