The two boxcars A and B have a weight of 25 000 Ib and 40 000 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 = 0.5. 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 R reenortivoly /Figure 1) Figure 1 of 1 B. C.
