To calculate the required power of a given electric locomotive, we apply the formula: N = F * V.
The value of the variables: F is the traction force of the electric locomotive (F = 200 kN = 200 * 10 ^ 3 N); V is the speed of the train (V = 72 km / h; in SI V = 20 m / s).
Let’s perform the calculation: N = F * V = 200 * 10 ^ 3 * 20 = 4 * 10 ^ 6 W (4 MW).
Answer: The power of a given electric locomotive is 4 MW.
