21. (Force and Motion II) An astronaut is rotated in a horizontal cen- trifuge at a radius of 5.0 m. i What is the astronaut's speed if the centripetal acceleration has a magnitude of 6.0g? (g is the gravitational acceleration) ii How many revolutions per minute are required to produce this acceleration? iii What is the period of the motion? Answer: i) 17.15 m/s ii) 32.7 rev iii) 1.83 s 21.
