Answer: 
Explanation:
Centripetal acceleration
is calculated by the following equation:
Where:
is the Earth's orbital speed
is the orbital radius

The answer to the question is 2,000 J. Hope this helps!
To solve this problem we will apply the concepts related to the kinematic equations of linear motion. For such an effect we will define the average speed, as the distance traveled in the established time.
Our values are given under the following conditions:



The final distance covered in those 10 seconds at
would be


Therefore the average speed would be the sum of those distances in the total travel time


Therefore the average velocity is 30.5m/s
Answer:For this equation you would have to take the numerator and multiply with the other one, which would leave you with 24/80 and if you want the simplified version it would be 3/10, hope this helps! :)
