Shuttle astronauts typically feel accelerations up to 3g, where g = 9.80 m/s. In r?
As their booster rockets separate, Space Shuttle astronauts typically feel accelerations up to 3g, where g = 9.80 m/s2. In their training, astronauts ride in a device where they experience such an acceleration as a centripetal acceleration. Specifically, the astronaut is fastened securely at the end of a mechanical arm that then turns at constant speed in a horizontal circle. Determine the rotation rate, in revolutions per second, required to give an astronaut a centripetal acceleration of 3.08g while in circular motion with radius 9.74 m.
Answer in revolution per second.

29.4 m/s/s=v^2*9.74 m
w^2= 3.01848 radians/sec
because there is 2*pi radians per revolution, then it comes out to;
1.7374 radians/sec* 1 rev/(2*pi rad)= 0.2765 rev/secSource(s): Yahoo Answers
