A satellite is in a circular orbit around an unknown planet. The satellite has a speed of 1.13 x 104 m/s, and the radius of the orbit is 3.77 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 9.53 x 106 m. What is the orbital speed of the second satellite?
