SUMMARY
The speed calculation for an artificial satellite traveling at an altitude of 230 km above the Earth's surface is confirmed to be accurate at v = 3 x 10^4 m/s. The gravitational acceleration at this altitude is g = 9.0 m/s², and the Earth's radius is 6370 km. To determine the time taken for one complete revolution, the centripetal acceleration must be provided by gravitational force, which can be calculated without knowing the satellite's mass. The discussion concludes that using the known velocity and radius allows for straightforward calculation of the orbital period.
