Q. A satellite is in a circular orbit around an unknown planet. The satellite has a speed of 1.55 104 m/s, and the radius of the orbit is 5.05 x10^6 m. A second satellite also has a circular orbit around this similar planet. The orbit of this second satellite has a radius of 8.45 x10^6 m. What is the orbital speed of the second satellite?
