A train consists of a 4300-kg locomotive pulling two loaded boxcars. The first boxcar has a mass of 12,700 kg and the second has a mass of 16,300 kg. Presume that the boxcar wheels roll without friction and ignore aerodynamics. The acceleration of the train is 0.235 m/s2.
With what force, in Newtons, do the boxcars pull on each other?
