A locomotive is pulling 19 freight cars, each of which is loaded with the same amount of weight. The mass of each freight car (with its load) is 37,000 kg. If the train is accelerating at .22 m/s^2 on a level track, what is the tension in the coupling between the third and fourth cars? (The car nearest the locomotive is counted as the first car, and friction is negligible.)

A 36500 lb engine is pulling two freight
cars up a 2.4 % incline. The weight of the first freight car is
36500 lbs, and the weight of the second freight car is 10000 lbs.
The train is accelerating at 0.43 ft/s2 as it goes up the hill.

#8 Mechanical Equilibrium: suspended blocks A 10.4 kg mass is suspended from the ceiling with a cable of negligible mass. A 12.5 kg mass is attached (and suspended below) the 10.4 kg mass with a cable, also of negligible mass. What are the tensions, respectively, connecting the 10.4 kg mass to the ceiling (cable 1) and the cable connecting the 12.5 kg mass to the 10.4 kg mass (cable 2) O A. cable 1: 102 N; cable 2: 123 N...

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 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...

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...
