The two boxcars A and B have a weight of 17 000 lb and 38 000 lb , respectively. They are freely coasting down the incline when the brakes are applied to all the wheels of car A . The coefficient of kinetic friction between the wheels of A and the tracks is μ k = 0.6. The wheels of car B are free to roll. Neglect their mass in the calculation. Suggestion: Solve the problem by representing single resultant normal forces acting on A and B , respectively.
Determine the magnitude of the force in the coupling C between the two cars.
