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...

(c) If the currents are in opposite directions (antiparallel), how do the answers to parts (a) and (b) change? What is the magnitude of the force between the two wires? ___N...
A light-rail train going from one station to the next on a straight section of track accelerates from rest at 1.20 m/s2 for 12.6 s . It then proceeds at constant speed for 1300 m before slowing down at 2.00 m/s2 until it stops at the station. What maximum velocity does the train achieve after leaving the station? What is the distance between the stations? How much time does it take the train to go between the stations?
