14. REASONING At the maximum speed, the maximum centripetal force acts on the tires, and static friction supplies it. The magnitude of the maximum force of static friction is specified by Equation 4.7 as MAX ss N f F µ = , where s is the coefficient of static friction and F N is the magnitude of the normal force. Our strategy, then, is to find the normal force, substitute it into the expression for the maximum frictional force, and then equate the result to the centripetal force, which is 2 c / Fm v r = , according to Equation 5.3. This will lead us to an expression for the maximum speed that we can apply to each car. SOLUTION Since neither car accelerates in the vertical direction, we can conclude
