well the centrifugal force is just equal but opposite to the centripetal force
which i don't know...and i don't know the MASS of the car and thus can't calculate the weight
Friction provides the centripetal force necessary for a car to reval around a circular flat racetrack. What ios the maximum speed at which a car can travel safely around a track of radius 80m if the coefficient of friction between the tyres and road is 0.3?
I really have no idea how to...
