D.
All follow an elliptical path that has two foci, rather than a circular path.
Kepler found paths are elliptical, not circular
The average speed is 116.66m/s.
Given - The path traced is 14km , time for jogging is 2 hrs=120min
To find the average speed-
- Speed refers to the ease of the movement and degree of mobility as a result of force application.
- Due to this there is involvement of velocity.
- Journey of average speed is the cumulative of distances and time.
- Kinetic theory refers to the Boltzmann constant connecting to the standards of distance traversed.
calculations-

Speed= 14 000 / 120
= 116.66m/s

Answer:
Motion of a racing car on a circular track
Explanation:
Uniform circular motion means the motion of the object is in a circle with a CONSTANT SPEED.
The racing car will accelerate during its motion. Hence, it is not a uniform circular motion.
The earth is 4.54 billion years old.
