Whenever two Apollo astronauts were on the surface of the Moon, a third astronaut orbited the Moon. Assume the orbit to be circular and 120 km above the surface of the Moon, where the acceleration due to gravity is 1.48 m/s2. The radius of the Moon is gravity is 1.48 m/s2. The radius of the Moon is 1.70 times 106 m. Determine the astronaut's orbital speed. Determine the period of the orbit.Explanation / Answer
mv^2/r=mg
So
orbital speed=v=sqrt(gr)=sqrt(1.48*(120000+1700000))=1641.22m/s
t=2pi*r/v=6967.62 sec
