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, w. Click the hint button again to remove this 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

Answer 1

@ - 88.2 Centeripetal aueleration (ac)=w2r r=radius=4.88m, ac=88.2m/s? ace u = 4.88 4.25 rad's Aug linear speed (u) = rue (4.25) (4.88) - 20.74 MIS Ay 6
