Answer:
The answer to the question is;
Based on their acceleration the rank of the satellites from largest to smallest is.
B >→ A >→ E >→ C >→ F >→ D.
Explanation:
Acceleration is given by
Therefore the acceleration for each of the satellite is given by
Satellite A) = 5.12 m/s²
Satellite B) = 10.24 m/s²
Satellite C) = 2.56 m/s²
Satellite D) = 0.16 m/s²
Satellite E) = 2.88 m/s²
Satellite F) = 0.64 m/s²
Therefore in order of decreasing acceleration, from largest to smallest we have
Satellite B) > Satellite A) >Satellite E) >Satellite C)>Satellite F)>Satellite D).
