A train locomotive pulls a train with a mass of 1.00 ✕ 107 kg on level rails. The locomotive exerts a constant force of 6.70 ✕ 105 N on the train. How much time does it take to increase the speed of the train from rest to 78.0 km/h? (Ignore any resistance force from the rails on the wheels of the train. Enter your answer in minutes.)
