A satellite is in a circular orbit around an unknown planet. The satellite has a speed of 1.70 × 104 m/s, and the radius of the orbit is 5.80 × 106 m. A second satellite also has a circular orbit around this same planet. The orbit of this second satellite has a radius of 8.50 × 106 m. What is the orbital speed of the second satellite?
My physics optional extra work: This would be helpful so I can compare the solutions here as I do the work by myself.
