The car moves along the highway at a speed of 90 km / h. Find the thrust of its engine

The car moves along the highway at a speed of 90 km / h. Find the thrust of its engine if it is known that the car develops power of 75kW.

To find the value of the thrust force of the engine of the specified vehicle, we apply the formula: Ftyar = N / V.

Variables: N is the power of the specified vehicle (N = 75 kW = 75 * 10 ^ 3 W); V – speed of movement (V = 90 km / h = 25 m / s).

Let’s make a calculation: Ftyag = N / V = 75 * 10 ^ 3/25 = 3 * 10 ^ 3 N.

Answer: The thrust force of the engine of the specified vehicle is 3 kN.
