Stopping Distance

As you double your speed from 20 mph to 40 mph, what do you think will happen to the distance you need to come to a complete stop? Estimate in terms of a number (E.G., 1.5 times, 3 times, etc.)

  7. We think that as you double your speed your braking distance will add 1 to 2 seconds to stop. Because your momentum will take you farther.
