Calculate the engine power of a car moving at a speed of 54 km / h, if the resultant force is 5KN.

Task data: V (speed of a given vehicle) = 54 km / h (in SI V = 15 m / s); F (resultant of all forces) = 5 kN (5 * 10 ^ 3 N).

The engine power of a given car is equal to the product of its speed and the resultant of all forces: N = F * V.

Let’s perform the calculation: N = 5 * 10 ^ 3 * 15 = 75 * 10 ^ 3 W (75 kW).

Answer: The engine power of a given vehicle is 75 kW.
