When transporting cargo, the dump truck develops a power of 25 kW. What kind of work is done by the pulling force of a dump truck in 4 minutes?
These tasks: N (the power that the used dump truck developed) = 25 kW (25 * 10 ^ 3 W); t (duration of dump truck operation) = 4 minutes (in SI t = 240 s).
To calculate the work of the traction force of the used dump truck, we apply the formula: A = N * t.
Calculation: A = 25 * 10 ^ 3 * 240 = 6 * 10 ^ 6 J (6 MJ).
Answer: 6.
