1. The problem statement, all variables and given/known data A driver in a car is on a level road traveling at a speed of "v". He puts on the brakes and they lock and skid rather than roll. I have to use the Work-Energy Theorem to give an equation for the stopping distance of the car in terms of "v". the acceleration of gravity "g" and the coefficient of kinetic friction "u(k)" between the tires and the road. 2. Relevant equations W = EK(f) - EK(i) 3. The attempt at a solution I attempted to use various formulas I have that use friction and gravity but came up to no success. I am hoping someone else knows what they are doing.
