A curve on a highway has a radius of curvature r . The curved road is banked at T with the horizontal. If the coefficient of static friction is n, (a) Obtain an expression for the maximum speed v with which a car can go over the curve without skidding. (b) Find v if r = 100 m, T = 30, g = 9.8 m/s2 , n = 0.25
