A car travels on a flat circular path of radius 250 m with constant speed 20 m/s :-
When car is at A, it acceleration is 1.6 m/s2 in the west direction.
Acceleration of car at A will depend on the sense in which car is moving i.e. clockwise or anticlockwise.
Frictional force acting on car will always be towards centre of circle.
Velocity of car remains constant as it moves on circle.
