Question: The EF Express, a train similar to the one shown above, has 4 locomotives (77 tons each) and 80 coal cars (38 tons each). The train is going down a 1.8% incline. Use positive as the direction the train is going.

The engines are started and the tractive force provided by each locomotive is 12700 lbs. What is the acceleration of the train as it goes down the 1.8% incline? (include units with answer)

What is the magnitude of the force in the coupling between the locomotives and the cars while going down the 1.8% incline with a tractive force provided by each locomotive of 12700 lbs? (include units with answer)

The engines are turned off so there is no tractive force. The train is moving at 14 mph down the incline. What is the required magnitude of the braking force to bring the train to a stop in 1900 ft? (include units with answer)
