Astronauts use a centrifuge to simulate the acceleration of a rocket launch. The centrifuge takes 40.0 s to speed up from rest to its top speed of 1 rotation every 1.50 s . The astronaut is strapped into a seat 7.60 m from the axis. a.What is the astronaut's tangential acceleration during the first 40.0 s ? b. How many g's of acceleration does the astronaut experience when the device is rotating at top speed? Each 9.80 m/s2 of acceleration is 1 g.

Astronauts are spun in a device called a centrifuge as a physical test before they fly in space. With what linear speed would an astronaut need to be spinning in order to experience an acceleration of 3 g's at a radius of 10.0 m? (1 g = 9.80 m/s^22)

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...
