Respuesta :
The moon is 384,000 km away from the Earth. It revolves around the earth in 27.3 days. (pi = 3.14)
Speed is rv = r 2pi/T
v = 384,000 2pi/27.3 * 86400
= 27.9 km/s
Good luck :)

Answer:
It is 7850 m/s
Explanation:
The orbital velocity is given by
[tex]v = \sqrt{\frac{GM}{r}}[/tex]
where, G be the universal gravitational constant, M be the mass of earth and r be the distance of moon from earth.
[tex]G = 6.67\times 10^{-11} Nm^{2}/kg^{2}, M = 5.98\times 10^{24}kg, r = 6.47\times 10^{6}m[/tex]
[tex]v = \sqrt{\frac{6.67\times 10^{-11}\times 5.98\times 10^{24}}{6.47\times 10^{6}}}[/tex]
v = 7850 m/s
