In a railroad classification yard, a 69-Mg freight car moving at 1.5 m/s at A encounters a retarder section of track at B which exerts a retarding force of 36 kN on the car in the direction opposite to motion. Over what distance x should the retarder be activated in order to limit the speed of the car to 4.3 m/s at C? 168 m 3.5 m A B (Vertical scale exaggerated) Answer:x = i m
