Determine the work done by the electric locomotive in 2 hours, evenly moving the train with an average

Determine the work done by the electric locomotive in 2 hours, evenly moving the train with an average speed of 54 km / that if the traction force is 50 kN.

To determine the work performed by the used electric locomotive, we use the formula: A = F * S = F * V * t, where F is the traction force of the electric locomotive (F = 50 kN = 50 * 10 ^ 3 N); V – travel speed (V = 54 km / h, in SI V = 15 km / h); t is the duration of the movement of the electric locomotive, the train (t = 2 hours, in SI t = 7200 s).

Let’s perform the calculation: A = F * V * t = 50 * 10 ^ 3 * 15 * 7200 = 5.4 * 10 ^ 9 J (5.4 GJ).

Answer: For 2 hours of moving the train, the electric locomotive performed work of 5.4 GJ.
