The general relationship between the orbital distance and speed can be found by equating the centripetal force with gravitational force.
The radius of the second orbit increases by a factor of 9.09/2.76 = 3.29
Therefore, the orbital speed will change by a factor of sqrt (1/3.29) = 0.55
A satellite is in a circular orbit around an unknown planet. The satellite has a speed of 1.01 x 104 m/s, and the radius of the orbit is 2.76 x 106 m. A second satellite also has a circular orbit around this same planet. The orbit of this second satellite has a radius of 9.09 x 106 m. What is the orbital speed of the second satellite?
