A road safety problem. A corner in a flat road has a constant radius of r = 25 m. Air resistance and rolling resistance are zero. (Hey, I want a car like that!), and the car is travelling at constant speed. What is the maximum speed our car can go round this corner without skidding? For a reasonably clean, dry road, take the coefficients of static and kinetic friction to be us = 1.0 and µz = 0.80. Hint: What horizontal force is acting on the car? Maximum speed. kph Enter answer here
