Asked Nov 2, 2019

A train locomotive pulls a train with a mass of 1.00 ✕ 10^{7} kg on level rails. The locomotive exerts a constant force of 6.70 ✕ 10^{5} 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.)

Step 1

**Given information:**

Mass of the train (m) = 1.0 × 10^{7} Kg

Force the locomotive can exert (F) = 6.7 × 10^{5} N

Final velocity that is needed to be achieved (v) = 78 kmph

Step 2

According to Newton 2nd law the forced exer...
