What kind of work does a 5 kW electric motor do in 10 minutes?

The power of the electric motor can be calculated using the formula:
N = A / t, where N is the power of the electric motor (N = 5 kW = 5 * 10 ^ 3 W), A is the useful mechanical work performed by the electric motor (J), t is the operating time of the electric motor (t = 10 min = 10 * 60 s = 600 s).
Let us express and calculate the useful work of the electric motor:
A = N * t = (5 * 10 ^ 3) * 600 = 3,000,000 J = 3 * 10 ^ 6 J = 3 MJ.
Answer: The useful work of the electric motor is equal to 3 MJ.
