Question

what allows cars to travel on a racetrack at very high speeds without skidding? answer options: select one of four length of the track increased air resistance angle of the bank incline height of the bank incline

Explanation:

To determine what allows cars to travel at high speeds on a racetrack without skidding, we analyze each option:

• "Length of the track" relates to the distance available, not to preventing skidding.
• "Increased air resistance" would slow the car down and is not related to preventing skidding.
• "Angle of the bank incline" is crucial. The banked angle provides a component of the normal force that acts as a centripetal force, helping the car to turn without relying solely on friction, which allows higher speeds without skidding.
• "Height of the bank incline" is not the key factor; it's the angle that matters for providing the necessary centripetal force component.

Answer:

Angle of the bank incline
