A 6.0 m long ladder AB leans against a smooth wall making an angle of 60º with the floor (Figure 3). The ladder is uniform and has a mass of 20.0 kg. (a) Determine the forces exerted on the ladder by the floor and the wall (i.e. at A and B, respectively). (b) Determine the minimum value of the coefficient of static friction to prevent the ladder from slipping.
