Determine the power of the locomotive engine, knowing that it covers 58 km in 1 hour. The traction force of the diesel locomotive is 155 kN.

In the condition of the problem, it is given that the diesel locomotive for the time t = 1 hour = 3600 s covers the path S = 58 km = 58000 m, developing a thrust force F = 155 kN = 155000 N. To determine the engine power of the diesel locomotive N, we use the definition of the concept of power as work done per unit of time N = A / t. The work is determined by the formula A = F ∙ S, then:

N = F ∙ S / t.

Substitute the values \ u200b \ u200bof the quantities in the calculation formula and find the power:

N = (155000 N ∙ 58000 m) / 3600 s; N ≈ 2,500,000 W = 2.5 MW.

Answer: the engine power of the locomotive is 2.5 MW.
