What kind of work does the car engine do against frictional forces during uniform motion in 5 s with an engine power of 50 kW?

What kind of work does the car engine do against frictional forces during uniform movement in a time of 5 s? with an engine power of 50 kW?
t = 5 s
N = 50 kW = 50000W
A -?
Since the car moves evenly, all the work of the engine goes to overcome the friction force. The engine power N is the work A performed in a unit of time t, N = A / t. Let us express the values of the work A = N * t. Substitute the values into the formula A = 50,000W * 5 s = 250,000 J.
Answer: the engine of the car against frictional forces did the work
