Best ResponseYou've already chosen the best response.1\[T ^{2} = (4\pi ^{2}/GM) \times R ^{3}\]\[(24)^{2} = (4\times3,14^{2}\div(6,67\times10^{11}\times5,98\times10^{24})) \times R ^{3}\]\[R \approx 17,9\times10^{4}m\]\[mV ^{2}/R = GMm/R ^{2}\]\[V = \sqrt{6,67\times10^{11}\times5,98\times10^{24}/ 17,9\times10^{4}}\]\[V \approx 6,95\times10^{4}m/s\] ;)
