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 circular motion and safely negotiate the curve. A car rounds a banked curve with banking angle ? = 23.2° and radius of curvature 168 m. (a) If the coefficient of static friction between the car's tires and the road is ?s = 0.393, what is the range of speeds for which the car can safely negotiate the turn without slipping? vlow=? m/s. vhigh= ? m/s b)What is the minimum value of ?s for which the car's minimum safe speed is zero? Note that friction points up the incline here.

A velodrome has an aggressively banked curve, where the surface makes an angle of 58.9 degrees with the horizontal. If you are biking around this curve (such that your path traces a horizontal circle with radius 21.7 m as you go around the turn), and the coefficient of static friction of your bike tires with the velodrome surface is 0.617, what is the minimum speed that you can go before starting to slip down the ramp? Give your answer in km/hr.
Engineers who design roads typically “bank” (incline) curves in such a way that a car traveling at the recommended speed does not have to rely on friction between its tires and the road in order to round the curve. Suppose the radius of curvature of a road segment is 55 m, and the recommended speed is 45 km/hr. At what angle should the curve be banked?
