The locomotive runs 0.5 km for 30 seconds, moving evenly. At the same time, it develops a power of 0.5 mW. Determine the traction force of the locomotive.

The power of the locomotive can be calculated using the formula:

N = F * V, where N is the power developed by the locomotive (N = 0.5 MW = 0.5 * 106 W), F is the traction force of the locomotive (N), V is the speed of the locomotive (V = S / t, where S is the distance traveled by the steam locomotive (S = 0.5 km = 500 m), t is the time the locomotive moves (t = 30 s)).

N = F * V = F * S / t.

Let us express and calculate the traction force of a steam locomotive:

F = N * t / S = 0.5 * 106 * 30/500 = 30,000 N = 30 kN.

Answer: The traction force of the locomotive is 30 kN.
