A train consists of a 4300kg locomotive pulling two loaded boxcars. The first boxcar has a mass of 12,700kg and the second 16,300kg. Presume that the boxcar wheels roll without friction and ignore aerodynamics. The acceleration of the train is 0.578m/s^2 a)With what force, in Newtons, do the boxcars pull on each other? I am confused here. Do they pull on each other with the same force? They can't since they don't weigh the same, correct? 0.578=T/12700 T=7340.6 0.578=T/16300 T=9421.4 b) With what force do the locomotive and first boxcar pull on each other? I can use the same steps from a) for this one c)With what force must the tracks push on the locomotive? would the force be equal to the weight?
