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 train at 0.042 meters/second2. What is the magnitude of the force in Newtons in the coupling between the engine and the first rail car?

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...

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...

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 43 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 friction tractive force F which gives the train forward motion, whereas the car wheels roll freely. Also, determine...

A mini train is moving at a constant speed along a straight, horizontal track. The train consists of an engine, which is in front, and one car that is being towed by the engine by a cable. The engine and car are not touching. There is a coefficient of kinetic friction of between the engine and the track, and between the car and the track. The coefficient is the same for both; it is 0.100. The engine has a mass...
