Question

An engine is used to pull a train of two cars outof a mine. The floor slopes upward at an angle of 28o.Each car has a mass of 1.1x104 Kg and normally travelswithout friction on the tracks. The engine can exert a maximumforce of 1.2x105 N on car A. If the engineer againthrottles back so that the force exerted by the engine on car Adecreases at the constant rate of 2.7 N per second, how long beforethe train stops moving up the track? Assume the original speed was2.0 m/s An engine is used to pull a train of two cars outof a mine.
