Homework 21. The International Space Station orbits at an altitude of roughly 400 km.Assuming a circular orbit, what is the orbital velocity of the ISS? What is the period of its orbit?2v2a. For two moons (Moon A and Moon B) with the same mass, both in circular orbits aboutMars, how many times more quickly or slowly is Moon B moving along its orbit if it is 4 timesfarther from Mars’ center than Moon A?b. Now, if Moon A is 3 times more massive than Moon B, how much faster or slower will MoonB’s orbital velocity be (relative to that of Moon A)?3.
