Question 2 The man is pushing the dresser (of uniform weight) across a laminate surface. The dresser has a weight of 80 Ib, and the coefficient of friction, µ, = 0.25. If the man pushes in the direction 30 2m shown. a) Determine the smallest force F 1.5m necessary to slide the dresser. (slipping). Fs=22016 b) Determine the smallest F necessary to tip the dresser. F;= 267.5 Hb c) Which way will the dresser move first? d) The man has a weight of 150 lb. given the answer to part a and b, determine the minimum coefficient of friction between the man's shoes and the floor so that he doesn't slip. Ms= 0.17}
