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 9 g (88.2 m/s 2 ) without losing consciousness, (a) If a human centrifuge has a radius of 4.50 m, what angular speed results in a centripetal acceleration of 9 g ? (b) What linear speed would a person in the centrifuge have at this acceleration?

An astronaut is being tested in a centrifuge. The
centrifuge has a radius of 11.0 m and, in starting,
rotates according to 0 = 0.320t², where t is in
seconds and is in radians. When t = 4.90 s, what are
the magnitudes of the astronaut's (a) angular
velocity, (b) linear velocity, (c) tangential
acceleration, and (d) radial acceleration?

NASA uses large centrifuges to study the effects of large forces on astronauts prior to their going into space. A subject in the 20-G centrifuge, which has a radius of 9.5 m, can have a centripetal acceleration as large as 20.0g, where g equals 9.81 m/s2. What is the tangential speed of the subject?
