How fast must the astronaut''s head be moving

Reference no: EM13106170

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 8.84m 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 12.5g. 1. How fast must the astronaut's head be moving to experience this maximum acceleration? 2. What is the difference between the acceleration of his head and feet if the astronaut is 2.00m tall? 3.How fast in (revolutions per minute) is the arm turning to produce the maximum sustained acceleration?
