The distance required for a car to come to a stop will vary depending on how fast the car is moving. Suppose that a certain car traveling down the road at a speed of 20 m / s 20 m/s can come to a complete stop within a distance of 80 m 80 m . Assuming the road conditions remain the same, what would be the stopping distance required for the same car if it were moving at speeds of 10 m / s 10 m/s , 40 m / s 40 m/s , or 5 m / s 5 m/s ?
