I am having a lot of trouble with this problem: A car is traveling at 45.0 km/h on a flat highway. If the coefficient of friction between road and tires on a rainy day is 0.100, what is the minimum distance in which the car will stop? I know it uses the delta X kinematics equation, so I should use friction to figure out the acceleration, but we haven't covered this material in class and I am at a loss for how to proceed. Also, will I be considering four systems, one for each tire in contact with the road? Thanks, any tips are appreciated!
