The traction force of the locomotive is 240,000N. Engine power 3000kW.

The traction force of the locomotive is 240,000N. Engine power 3000kW. How long does it take for a train to cover a distance of 15 km with uniform movement?

To determine the duration of the locomotive movement, we use the formula: N = F * V = F * S / t, whence t = F * S / N.

Values of the variables: F – traction force of the locomotive (F = 240,000 N = 240 * 10 ^ 3 N); S – distance traveled (S = 15 km = 15 * 10 ^ 3 m); N is the power of the motors (N = 3000 kW = 3 * 10 ^ 6 W).

Let’s perform the calculation: t = F * S / N = 240 * 10 ^ 3 * 15 * 10 ^ 3 / (3 * 10 ^ 6) = 1200 s or 20 minutes.

Answer: The diesel locomotive will need 20 minutes to travel 15 km.
