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.
The expected measurements should range as follows: 5, 10, 15, 20, and 25 meters.
The gravitational force between Royce and Earth would double by the age of 16. Newton’s law of universal gravitation states that the gravitational force is proportional to the masses involved and inversely proportional to the square of the distance between them. At age 10, Royce weighed 30 kg, and by age 16, he weighed 60 kg. Since his mass doubled from 10 to 16 years, this results in a corresponding doubling of the gravitational force.
