The 20 g centrifuge at nasa's ames research center in mountain view, california, is a horizonatal, cylinderical tube 58 ft long and is represented in the figure. The machine generates an acceleration up to 20-times earth's gravity. Assume an astronaut in training sits in a seat at one end, facing the axis of rotation 29 ft away. what is the magnitude of astronaut velocity, if an astronaut is given a centripetal acceleration of 17.6 g? What is the period of the motion?
