Banked curves are designed so that the radial component of the normal force on the car rounding the curve provides the centripetal force required to execute uniform clrcular motion and safely negotlate the curve. A car rounds a banked curve with banking angle θ-27.1° and radius of curvature 157 m. (a) It the coefficient of static friction between the car's tires and the road is -0.316, what is the range ot speeds for which the car can safely negotiate the turn...
