MY NOTES ASK YOUR TEACHER 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 Apply the expression for the centripetal acceleration, expressed in terms of the angular speed, co. Click the hint button again to remove this hint. (a) If a human centrifuge has a radius of 3.87 m, what angular speed (in rad/s) results in a centripetal acceleration of 99? rad/s (b) What linear speed (in m/s) would a person in the centrifuge have at this acceleration? m/s
