A 2400-lb (= 10.7-kN) car traveling at 30 mi/h (= 13.4 m/s) attempts to round an unbanked curve with a radius of 200 ft (= 61.0 m). (a) What force of friction is required to keep the car on its circular path? (b) What minimum coefficient of static friction between the tires and road is required?

Therefore the magnitude of frictional force on the car is 3210 N .
