15-6. A train consists of a 50-Mg engine and three cars, each having a mass of 30 Mg. If it takes 80 s for the train to increase its speed uniformly to 40 km/h, starting from rest, determine the force T developed at the coupling between the engine E and the first car A. The wheels of the engine provide a resultant frictional tractive force F which gives the train forward motion, whereas the car wheels roll freely. Also, determine...

A freight train consists of 4 engines at the front, followed by 30 rail cars. Both the engines and rail cars have the same mass of 722655 kilograms each. Each engine exerts the same force backward on the track to push the train forward. The total force of friction on the entire train is 698119 Newtons and is evenly distributed among all of the cars and engines. Even with this friction present, the train engines are able to accelerate the...

A toy freight train consists of an engine and three identical cars. The train is moving to the right at constant speed along a straight, level track. Three spring scales are used to connect the cars as follows: spring scale A is located between the engine and the first car; scale B is between the first and second cars; scale C is between the second and third cars. (a) If air resistance and friction are negligible, what are the relative...

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...

A freight train consists of two kg 1000.8 4 − × engines and 45 cars with average masses of kg 1050.5 4 × . (a) What force must each engine exert backward on the track to accelerate the train at a rate of 2 –2 m/s 10.005 × if the force of friction is N 1050.7 5× , assuming the engines exert identical forces? This is not a large frictional force for such a massive system. Rolling friction for trains...

If it takes time 31 s for the tugboat of mass m = 46 Mg to increase its speed uniformly to v = 24 km/hr starting from rest, determine (a) the force of the rope on the tugboat. Also, the propeller provides the propulsion force F which gives the tugboat forward motion, whereas the barge moves freely. Determine (b) the force F the tugboat...

Your old toy train from pre-school days consists of three cars: M_1 = 0.4 kg. M_2 = 0.4 kg, and M_3 = 0.1 kg. You pull the cars with a force F = 5.0 N (red arrow in the picture). The coefficient of kinetic (rolling) friction between all three cars and the ground is mu_k = 0.14. What is the difference in the tensions between the two ropes, F_TA - F_Tb? Give your answer in Newtons to at least three...
