Maybe I'm thinking way too deep for this problem, but here goes: -A car is traveling 11.7 m/s on a flat road. -Acceleration of gravity = 9.8 m/s^2 -The coefficient of friction between the road and the tires is 0.156 -What is the minimum distance in which the car will stop? I tried to start this problem, but I really need to know the car's weight to figure out the normal force (Fn - force exert on the car by the road). The car's weight will also give me the horizontal force, which I could use it to find the car's deceleration. Then find the time period from start to stop to find the distance it travelled. Is there another aspect of this problem that I fail to notice? Any hints would help.
