18. Verify that the linear speed of an ultracentrifuge is about 0.50 km/s, and Earth in its orbit
is about 30 km/s by calculating:
(a) The linear speed of a point on an ultracentrifuge 0.100 m from its center, rotating at
50,000 rev/min.
(b) The linear speed of Earth in its orbit about the Sun (use data from the text on the radius of
Earth's orbit and approximate it as being circular).

A rotating 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 210 m in diameter, what angular velocity would produce an "artificial gravity" of 9.80 m/s2 at the rim? ________ rpm

Q1: Two planets of the same mass m are acted on only by the gravitational force of one upon the other. If the distance r between the planets is kept constant, what is the angular velocity of the line joining them?
