When a roadway is _________, it supplies the centripetal force without the need to rely on friction.A. LevelB. UnpavedC. ClippedD. Banked

To answer the question, we need to consider the concept of banked roads in physics, particularly in the context of circular motion.

When a roadway is banked, it means that the road is angled such that it can help to provide the necessary centripetal force for a vehicle to turn safely. This is especially important for vehicles moving at higher speeds, as it reduces reliance on friction between the tires and the road. A banked road enables vehicles to maintain their path in a curve primarily through the normal force exerted by the road surface, which is directed towards the center of the circular path.

On the other hand, a level roadway does not provide any additional support for centripetal force and relies entirely on friction. Unpaved and clipped roads also do not have this effect.

Thus, the correct answer to the question is:

Final Answer

D. Banked
