The centre of mass of a system cannot change its state of motion, unless there is external force acting on it. Yet the internal force of the brakes can bring a car to rest. Then

View answer and explanation

Correct option: C

The car is stopped by the road

The correct answer is C (The car is stopped by the road) because the external force of friction between the tires and the road is what ultimately brings the car to rest.
