The reason of a banked curve is to allow vehicles tomaneuver during the turn without relying on static tire friction to remain on the curve. An accident investigator is trying to decide whether or not a highway clover leaf on-ramp speed limit sign is correct for a banked curve with a 12.0 degree banking angle. Suppose the curve has a radius of 67 m. (a) what must the cautionary speed be for this curve? (b) If a 1200kg vehicle attempts to make the turn at a higher speed than the cautionary speed, frictional force must provide the additional centripetal force to keep the vehicle from sliding. What is the frictional force necessary to keep the car from sliding suppose the driver maintain a constant velocity of 95 km/h (59mph) ?
