Alocomotive is pulling 11 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 0.58 m/s2 on a level track, what is the tension in the coupling between the second and third cars?

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
