Ahuman centrifuge to test the effects of high acceleration on the human body, the national aeronautics and space administration (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 with a radius of 15 m.
if the astronauts in this centrifuge experience a centripetal acceleration 9.0 times that of gravity, what is the linear speed of the capsule?
