Question

question:
what allows cars to travel on a racetrack at very high speeds without skidding?

answer options:
select one of four
angle of the bank incline\theight of the bank incline
length of the track\tincreased air resistance

Explanation:

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

• The angle of the bank incline is crucial. When a racetrack is banked, the normal force from the track surface has a horizontal component that provides the necessary centripetal force for the car to move in a circular path at high speeds, preventing skidding.
• The height of the bank incline doesn't directly relate to the centripetal force needed to prevent skidding.
• The length of the track affects the distance the car travels but not the skidding prevention at high speeds.
• Increased air resistance would slow the car down and is not related to preventing skidding on the track.

So the angle of the bank incline is the correct factor.

Answer:

A. Angle of the bank incline
