Reference no: EM13240954

A train has 4 locomotives (73 tons each) and 60 coal cars (42 tons each). The train is going down a 2.4% incline. Use positive as the direction the train is going.

1) What is the mass of the entire train?

2) What is the acceleration of the train if it is allowed to roll down the track (no friction, braking, or tractive force)?

3) What is the magnitude of the force in the coupling between the locomotives and the cars while rolling down the incline?
