A ladder is propped up on a rough floor with against a frictionless wall. The center of mass of the ladder is 10 ft from the bottom of the ladder, whose overall length is 25 ft, as shown in the figure. The ladder weighs 80 lbs. The coefficients of friction between the ladder and = 0.5 and uk = 0.3. (The wall is frictionless; i.e., µwall the floor are µs 0) What is the magnitude and direction of the force that the vertical wall pushes against the ladder? Give your answer in pounds.
