Under the action of a traction force of 1000 N, the car moves at a constant speed of 72 km / h. The engine power is equal.

The engine power of a car can be calculated using the formula:
N = F * V, where N – vehicle power (W), F – vehicle traction force (F = 1000 N), V – vehicle speed (V = 72 km / h = 72 * 1000/3600 = 20 m / s) …
Let’s calculate the engine power of the car:
N = F * V = 1000 * 20 = 20,000 W = 20 kW.
Answer: The power of the car engine is 20 kW.
