freight train consists of 2 engines at the front, followed by 28 rail cars. Both the engines and rail cars have the same mass of 361,165 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 899,976 N and is evenly distributed among all of the cars and engines. Even with this friction present, the train engines are able to accelerate the train at 0.036 meters/second2. What is the magnitude of the force in Newtons that each engine would need to exert on the train track
