no net force from the equation F=ma
if theres no mass or acceleration then theres no net force and when its constant velocity theres no acceleration

From the fact that the car is not accelerating, you would expect there to be no net force. Newtons law is that a body in motion remains in motion unless there is a net force.
However, the car is producing heat as it moves: heat in the engine, in the tires, in the surrounding air-flow, and that is a hint that energy is being lost through frictional force, and the car's engine is compensating for this 'force of friction" to keep the car at the same speed.
But while there IS a force of friction, and there IS a force from the engine, these cancel, and you have no net force.
So! You can be assured that however complex the situation is in terms of various forces, the facts the that car has a constant velocity, and is not turning (no radial acceleration) are enough to be certain that there is no net force.

Newtons First Law of Motion:
When there is no net force acting on an object, the object will either remain stationary, or continue moving at a constant velocity.
Therefore, since car is travelling at a constant velocity, there is no net force acting on it.
Amine and borat have literally no clue what they're talking about.
Cheers.

it has momentum instead which is in the units of : N.s
if you divide by the traveling time it will give you the equivalent average force
during the travel.
But the net force on the car , according to newton's second law, will remain 0. I hope that
you can visualize the difference.

F= ma
So, if there is any net force the car would accelerate or deaccelerate. However, in real life problems we have to keep the engine running to oppose the force of friction. So, when force of friction = applied force the car runs at constant velocity.

no, net force would create an acceleration, the force of gravity down on it is counter acted by the force of the ground
-
gravity pushes down on it so yes
