Max Reaction Time to Avoid Obstacle 95m Away

[QUOTE="axmls, post: 4971782, member: 488930"] Your problem is that it doesn't take the entire 95 meters to stop. In other words, this person will have room left over. That's where you figure in the reaction time. You'll need to use a formula that relates velocity, acceleration, and distance. Hint: the initial velocity is 25 m/s, and the final velocity is 0 m/s. After you find the distance traveled during deceleration, then you know how much distance is left over. Then you find out how long it takes to travel that distance going 25 m/s, and you'll know how much time the driver has to react. [/QUOTE]
