When a car’s velocity is positive and its acceleration is negative, what is happening to the car’s motion?

When the velocity of a car is positive and its acceleration is negative that means the car's speed is decreasing or we can say that car is decelerating.

for example - when we apply brakes, the acceleration is negative while velocity is still positive.

Acceleration is the rate of change of velocity.

The car's rate of change of position is decreasing. The car is moving but its rate of position increase is coming down.

The car will eventually come to a brief stop and begin traveling backward.

v=uf/(u-f)
