Consider again the problem of a car traveling along a banked turn. Sometimes roads have a "reversed" banking angle. That is, the road is tilted "away" from the center of curvature of the road. If the coefficient of static friction between the tires and the road is μs = 0.4, the radius of curvature is 25 m, and the banking angle is 14°, what is the maximum speed at which a car can safely navigate such a turn?

Part A. The sports car, having a mass of 1700 kg, is traveling
horizontally along a 20° banked track which is circular and has a
radius of curvature of ρ = 100 m. If the coefficient of
static friction between the tires and the road is
μs = 0.2 . Determine the maximum constant speed
at which the car can travel without sliding up the slope. Neglect
the size of the car.

Consider a car moving on a circular track of radius R with constant velocity v. The track is inclined at an angle β with respect to the ground, such that the interior of the track is lower than the exterior and the tangent of β is greater than the coefficient of static friction of the track µ.
