The moon Phobos orbits Mars (m = 6.42 x 10^23 kg) at a distance of
9.38 x 10^6 m. What is the Phobos'
orbital velocity?
[?] m/s

Explanation:

For a circular orbit v= with G = 6.6742 ×

Given m = 6.42 x 10^23 kg and  r=9.38 x 10^6 m

=> v = 2137.3 m/s

I hope this is the correct way to solve

as technology advances, new experiments often expose problems in accepted theories. c
