To find the power of the diesel locomotive used, we apply the formula: N = Fт * V.
Values of the variables: Ft – effective traction force (Ft = 400 kN = 400 * 10 ^ 3 N); V is the considered speed of the locomotive (V = 21.6 km / h = 6 m / s).
Let’s perform the calculation: N = Ft * V = 400 * 10 ^ 3 * 6 = 2.4 * 10 ^ 6 V = 2.4 MW.
Answer: The power of the diesel locomotive used is 2.4 MW.
