Answer to Question #347684 in Physics for CJames

Question #347684

A spacecraft is in orbit at an altitude of 100 km above the surface of the moon.

What is its speed? Mmoon = 7.34 x 1022 kg and Rmoon = 1.84 x 106 m

Expert's answer

"v=\\sqrt{G\\frac{M}{r}}\\\\\n=\\sqrt{6.67*10^{-11}*\\frac{7.34*10^{22}}{1.84*10^6+100*10^3}}=1589\\:\\rm m\/s"
