The traction force of the electric locomotive is 400 kN. If the locomotive moves for 1 hour

The traction force of the electric locomotive is 400 kN. If the locomotive moves for 1 hour at a speed of 21.6 km / h, then work is being done.

To calculate the work done by an electric locomotive within 1 hour, we apply the formula: A = N * t = F * V * t.

Values of variables: F – traction force of the electric locomotive (F = 400 kN = 400 * 10 ^ 3 N); V – speed of movement (V = 21.6 km / h = 6 m / s); t – duration of movement (t = 1 h = 3600 s).

Let’s calculate: A = F * V * t = 400 * 10 ^ 3 * 6 * 3600 = 86.4 * 10 ^ 6 J or 86.4 MJ.

Answer: In 1 hour, an electric locomotive will perform work equal to 86.4 MJ.
