The dresser has a weight of 80 lb and is pushed along the floor. If the coefficient of static friction at A and B is μ_s = 0.3 and the coefficient of kinetic friction is μ_k = 0.2, determine the smallest horizontal force P needed to cause motion. If this force is increased slightly, determine the acceleration of the dresser. Also, what are the normal reactions at A and B when it begins to move?
