Task data: t (duration of machine engine operation) = 10 s; A (work to be done by the machine) = 720 kJ (720 * 10 ^ 3 J).
The engine power of the used machine is calculated by the formula: N = A / t.
Calculation: N = 720 * 10 ^ 3/10 = 72 * 10 ^ 3 W (72 kW).
Answer: the engine of the used machine has a power of 72 kW.
