Problem
A car of mass 1200kg takes a circular turn of radius 50m on a level road.
(i) Identify the physical force that supplies the necessary centripetal force enabling the car to move in a circle.
(ii) Calculate the minimum value of the coefficient of static friction μs between the tyres and the road if the car is to negotiate the turn safely at a speed of 15ms−1.
(iii) If the actual coefficient of static friction available is 0.20, determine the maximum speed with which the car can negotiate the same turn without skidding.
