Question

Asked Nov 2, 2019

A freight train has a mass of 1.1 ✕ 10^{7} kg. If the locomotive can exert a constant pull of 7.4 ✕ 10^{5} N, how long does it take to increase the speed of the train from rest to 74 km/h?

Step 1

**Given information:**

Mass of the train (m) = 1.1 × 10^{7} Kg

Force the locomotive can exert (F) = 7.4 × 10^{5} N

Final velocity that is needed to be achieved (v) = 74 kmph

Step 2

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