10) (5p) "Three test subjects, lying side by side in couches inside a three-ton metal ball at the end of a 50-foot arm, will be whirled around a circular course at 24 revolutions per minute [...] in mock spacecraft flights," reads a NASA press release from May 10, 1966. Calculate the centripetal acceleration that an Apollo astronaut, located 14.0 m from the axis of rotation would be exposed to and express it in multiples of "g" (9.8m/s). The distance the metal capsule travels during one revolution is 2r.
