A curve of radius 69 m is banked for a design speed of 95 km/h.

If the coefficient of static friction is 0.40 (wet pavement), at what range of speeds can a car safely make the curve? [Hint: Consider the direction of the friction force when the car goes too slow or too fast.]

Express your answers using two significant figures separated by a comma.

    Engineering a highway curve. If a car goes through a curve too fast, the car tends to slide out of the curve. For a banked curve with friction, a frictional force acts on a fast car to oppose the tendency to slide out of the curve; the force is directed down the bank (in the direction water would drain). Consider a circular curve of radius R = 270 m and bank angle θ, where the coefficient of static friction between...
