A 16.0-m uniform ladder weighing 480 N rests against a frictionless wall. The ladder makes a 63.0° angle with the horizontal. (a) Find the horizontal and vertical forces the ground exerts on the base of the ladder when an 810-N firefighter has climbed 3.80 m along the ladder from the bottom. Horizontal Force magnitude direction Vertical Force ---Select--- magnitude direction ---Select--- V N N (b) If the ladder is just on the verge of slipping when the firefighter is 9.10 m from the bottom, what is the coefficient of static friction between ladder and ground?
