Exponential Question??
If a car traveling at a speed of V can break at an emergency stop at a distance X. Assuming all other conditions are similar if the traveling speed of the car doubles, the stopping speed will be 4x. (I worked that out)
A driver traveling at 40 km/h in a school zone can break to emergency stop in 3 meters. What would be the breaking distance of the car were traveling at 60 km/h.
2. The attempt at a solution
I have no idea how to figure this out. From what I've done, I think the number is going to be less the 7.5 but greater than 6. I'm not exactly sure how I got that though.
Any help would be Greatly Appreciated!
