Problem: A satellite is in a circular orbit around an unknown planet. The satellite has a speed of 1.80 x 104 m/s, and the radius of the orbit is 5.30 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 8.40 x 106 m.
Part A: What is the orbital speed of the second satellite?
I need help to find the orbital speed of the second satellite.
