A device for acclimating military pilots to the high accelerations they must experience consists ofa horizontal beam that rotates horizontally about one end while the pilot is seated at the other end. In order to achieve a radial acceleration of 33.9 m/s2 with a beam of length 5.91 m, what rotation frequency is required? Number Hz

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 3.82 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

Steve was subjected to accelerations in a horizontal "centrifuge". It is considered that such a device has a radius of 5.0 m and can generate a centripetal acceleration equivalent to 7 times the average gravitational acceleration on Earth. a) For this maximum acceleration, what is the modulus of the astronaut's speed along the circular path? b) At how many revolutions per minute should the rotation occur to achieve such acceleration? c) What is the period of this rotation?

As their booster rockets separate, Space Shuttle astronauts typically feel accelerations up to 3g, where g = 9.80 m/s2. In their training, astronauts ride in a device where they experience such an acceleration as a centripetal acceleration. Specifically, the astronaut is fastened securely at the end of a mechanical arm, which then turns at constant speed in a horizontal circle. Determine the rotation rate, in revolutions per second, required to give an astronaut a centripetal acceleration of 2.97g while in...

At its Ames Research Center, NASA uses its large 20-G centrifuge to test the effects of very large accelerations (hypergravity) on test pilots and astronauts. In this device, an arm 8.84 m long rotates about one end in a horizontal plane, and the astronaut is strapped in at the other end. Suppose that he is aligned along the arm with his head at the outermost end. The maximum sustained acceleration to which humans are subjected in this machine is typically...
