Some satellites move around Earth in polar orbits, that is, in a north to south direction, rather than west to east. Can scientists who want to put a satellite into a polar orbit take
advantage of Earth’s rotation to give the rocket a “boost”? Explain.

Thank you if you help me out.

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
