Hey guys, I got the following problem.
It seems east, btu I still have no idea how to get started on this oneWhenever two Apollo astronauts were on the surface of the moon, a third astronaut orbited the moon. Assume the orbit to be circular and 100km above the surface of the moon, where the acceleration due to gravity is 1.52 m/s. The radius of the moon is 1.70 x 106. Determine the astronauts orbital speed and the period of the orbit.
