Question

- As their booster rockets separate, Space Shuttle astronauts typically feel accelerations up to $3 g,$ where $g=9.80 \mathrm{m} / \mathrm{s}^{2}$ 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 $3.00 g$ while in circular motion with radius $9.45 \mathrm{m}$
