A diesel locomotive at a speed of 54 km / h develops a traction force of 400kN. What work is done to move the train during 1 minute?
To find the work done when moving the used diesel locomotive, we apply the formula: A = F * S = Ft * V * t.
Values of variables: Ft – traction force developed by the used diesel locomotive (Ft = 400 kN = 400 * 10 ^ 3 N); V – constant speed (V = 54 km / h = 15 m / s); t – duration of movement (t = 1 min = 60 s).
Calculation: A = Ft * V * t = 400 * 10 ^ 3 * 15 * 60 = 360 * 10 ^ 6 J = 360 MJ.
Answer: In the process of moving a diesel locomotive, work of 360 MJ is performed in 1 minute.
