20. A 30 ft ladder weighing 40 lb is leaning against a wall when the bottom begins to slide. If the coefficient of kinetic friction between the ladder and all surfaces is 0.2 and the angle between the ladder and the wall is 40 degrees, find the angular acceleration of the ladder and the forces at A and B. a = 0.51 rad/s? FA = 31.8 lb 2 78.7 degrees Fe = 13.8 lb 2 169 degrees - -
