Response:
The acceleration of car 2 is four times that of car 1.
Rationale:
Centripetal acceleration occurs when an object travels in a circular route. It can be expressed as:

In this scenario, two race cars are moving at consistent speeds around a circular course. Both automobiles are located at an equal distance from the center, but car 2 is operating at twice the speed of car 1.
Thus,

1 and 2 represent the first and second cars, respectively.

Consequently,

Therefore, car 2's acceleration is four times that of car 1.
