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.
(a)
If a human centrifuge has a radius of 4.06 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
