Solution: A 5 kg box rests on top of a 10 kg box. The friction coefficients between the 10 kg box and the floor are μs1 = 0.4 and μk1 = 0.3, and the friction coefficients between the 10 kg box and the 5 kg box are μs2 = 0.35 and μk2 = 0.25. If a horizontal force of 50 N is applied on the 10 kg box, draw a free body diagram for each box, with the appropriate values of each force.
