Human centrifuges are used to train military pilots and astronauts in preparation for high-g maneuvers. A trained, fit person wearing a g-suit can withstand accelerations up to about 9g (88.2 m/s2) without losing consciousness. HINT (a) If a human centrifuge has a radius of 4.88 m, what angular speed (in rad/s) results in a centripetal acceleration of 9g?  rad/s (b) What linear speed (in m/s) would a person in the centrifuge have at this acceleration?  m/s
