Question

Car a is traveling at twice the speed of car b. They both hit the brakes at the same time and undergo identical decelerations. How does the distance required for car a to stop compare with that for car b?

Answer 1

Well considering that car A is going twice as fast, than car B, it would most likely also take twice as long for car A to stop than for car B, so with that in mind, you would need twice as much distance.
