| February 9, 2021 | education
Task data: N (vehicle power) = 45 kW (45 * 10 ^ 3 W); t (engine running time) = 1 h (in SI t = 3600 s).
The work that the car engine must do is determined by the formula: A = N * t.
Let’s calculate: A = 45 * 10 ^ 3 * 3600 = 162 * 10 ^ 6 J (162 MJ).
Answer: For 1 hour of operation, the car engine will perform work at 162 MJ.
