I have been asked to review a junior physicist's calculations regarding an artificial satellite travelling 230 km above the earths surface where acceleration due to gravity is about 9.0m/s2. He calculated a velocity of 30000 m/s. And the radius of the earth was measured at about 6370km. Does his speed seem right? I don't even know if I have enough information to figure this out.(adsbygoogle = window.adsbygoogle || []).push({});
