A 14.0 m uniform ladder weighing 510 N rests against a frictionless wall. The ladder makes a 65.0-angle with the horizontal. (a) Find the horizontal and vertical forces (in N) the ground exerts on the base of the ladder when an 850-N firefighter has climbed 4.20 m along the ladder from the bottom. horizontal force magnitude v N direction towards the wall | vertical force magnitude ? N drection [0 V] (b} If the ladder is just on the verge of slipping when the firefighter is 2.30 m from the bottom, what is the coefficient of static friction between ladder and ground? 0.381 % It may be helpful to think first about the force the wall exerts on the |ladder. How is this related to the force that the ground exerts on the ladder? (c) What If? If cil is spilled on the ground, causing the coefficient of static friction to drop to half the value found in part (b), what is the maximum distance (in m) the firefighter can climb along the ladder from the bottom before the ladder slips? o m
