A 15 m uniform ladder weighing 500 N rests against a frictionless wall. The ladder makes a 60° angle with the horizontal. For this problem, the ladder is in equilibrium, sum of the forces and sum of the torques are zero. (a) Find the horizontal and vertical forces that the ground exerts on the base of the ladder when an 800 N firefighter is 4 meters from the bottom. (6) If the ladder is just on the verge of slipping when the firefighter is 9 m up what is the coefficient of static friction between the ladder and the ground? Nw Ng 500N 800N FF
