| June 21, 2021 | education
Data: N (the power that a given dump truck developed when transporting cargo) = 30 kW = 30 * 10 ^ 3 W; t (duration of work) = 45 minutes (in SI t = 2700 s).
To calculate the work done by a given dump truck, we apply the formula: A = N * t.
Calculation: A = 30 * 10 ^ 3 * 2700 = 81 * 10 ^ 6 J = 81 MJ.
Answer: In 45 minutes, a given dump truck completed work at 81 MJ.
