The athlete shown in the figure rotates a 1.00 kg discus along a circular path of radius 1.03 m. The maximum speed of the discus is 22.0 m/s. Determine the magnitude of the maximum radial acceleration of the discus. The 20-g centrifuge at NASA's Ames Research Center in Mountain View, California, is a horizontal, cylindrical tube 58 ft long and is represented in the figure below. Assume an astronaut in training sits in a seat at one end, facing the axis of rotation 29.0 ft away. Determine the rotation rate, in revolutions per second, required to give the astronaut a centripetal acceleration of 15.8 g.

Explanation / Answer

max. radial accelaration = v^2/r = 469.9 m/sec^2
