Whenever two Apolloastronauts were on the surface of the Moon, a third astronaut orbited the Moon. Assume the orbit to be circular and 397 km above the surface of the Moon, where the acceleration due to gravity is 12 m/s2. The radius of the Moon is 1.70 ✕ 106 m. Determine the astronaut's orbital speed. Determine the period of the orbit.
