James asks…Physics HELP:What is the minimum stopping distance for the same car traveling at a speed of 40 m/s?The minimum stopping distance for a car traveling at a speed of 30 {m/s is 60 m, including the distance traveled during the driver's reaction time of 0.50 s.What is the minimum stopping distance for the same car traveling at a speed of 40 m/s?Nancy answers:We need to assume that once the driver started applying the brakes, the deceleration was constant.
In the original situation,
