What is the relation between the vehicles speed and the vehicle’s stopping distance?

1. The higher the vehicle’s speed is, the shorter is its stopping distance.
2. There is no relation between them. The stopping distance is constant and does not depend on the vehicle’s speed.
3. The slower the vehicle’s speed is, the longer is the braking distance.
4. Correct answer: The higher the vehicle’s speed is, the longer is its stopping distance.

WhyThe higher the speed, the longer the stopping distance. It is never constant.
