Given that the mass of mars is (6.4191 * 10^23 kg), the mass of a satellite is (4300 kg), the radius of a uniform circular path of the satellite is (6231795.438 m), & the velocity of the satellite is (2622 m/s), what should the speed of the orbit be, if we want the satellite to take 8 times longer to complete one full revolution of its orbit?
