To test the effects of high acceleration on the human body, NASA has constructed a large centrifuge at the Manned Spacecraft Center in Houston. In this device, astronauts are placed in a capsule that moves in a circular path of radius 15 m. If the astronauts in this centrifuge experience a centripetal acceleration 7 times that of gravity (or "7 g's"), what must be the speed of the capsule?
