On a moving car in the horizontal direction, the engine thrust force is 850N, the friction force is 500N

On a moving car in the horizontal direction, the engine thrust force is 850N, the friction force is 500N, and the air resistance force is 350N. Find the resultant force.

Initial data: Fт (traction force of the car engine) = 850 N; Ftr. (friction force) = 500 N; Fc. (air resistance force) = 350 N.

The resultant force, which acts on the car, can be found by designing the acting forces on one axle: F = Ft – Ftr. – Fc.

Let’s make a calculation: F = 850 – 500 – 350 = 0 (therefore, the car is moving at a constant speed).

Answer: The net force is zero.
