Question
When a roadway is _________, it supplies the centripetal force without the need to rely on friction.A. LevelB. UnpavedC. ClippedD. Banked
Solution
The correct answer is D. Banked.
When a roadway is banked, the normal force provided by the roadway is split into two components. One component acts vertically upwards and balances the weight of the car, and the other component acts towards the center of the circle providing the necessary centripetal force for circular motion. This allows the car to maintain circular motion without relying on friction.
