a car is moving at 4m/s has 500N force driving it forward and air resistance of 500N. Describe the motion of the car

See the explanation below.

Explanation:

We know from Newton's second law that the sum of forces on a body is equal to the product of mass by acceleration. In this way, we have the following equation.

∑F = m*a

where:

∑F = sum of the forces [N] (units of Newtons)

m = mass of the car [kg]

a = acceleration [m/s²]

Therefore we have two forces one that drives the car forward and another that opposes the movement.

This tells us that the acceleration is zero and therefore the movement is with constant speed. That is, the speed does not vary during the movement of the vehicle.

this would be about 43%
