If the speed of a car is increased by 75%, by what factor will its minimum braking distance be increased, assuming all else is the same I am not sure what formulas i should use for this problem. Am i souposed to use the formula for Final velocity which is Velocity Final^2= Velocity Initial^2 + 2*acceleration*displacement I do not know how i would start this problem without knowledge of the variables. I am also not sure if this is even the right formula. I do not know the acceleration so i am not sure how it would work. Help!
