2.) A girl is running her toy trains on a level track. The train is made up of 5 cars and the locomotive. The locomotive (the engine that pulls) has a mass of 1.9 kg. Each car after the locomotive has a mass of 0.90 kg. Each car individually has a frictional drag of 2 N. Assume no frictional drag forces act on the locomotive. A.) Calculate the force acting on the locomotive that pushed the whole train (locomotive and all the cars) moving forward causing an acceleration of 0.25 m/s B.) What object is pushing the locomotive forward? C.) Calculate the force in hitch 2 and hitch 4 under the same conditions as reported above.
