Artificial gravity is produced in a space station by rotating it, so it is a noninertial reference frame. the rotation means that there must be a centripetal force exerted on the occupants; this centripetal force is exerted by the walls of the station. the space station in arthur c. clarke's 2001: a space odyssey is in the shape of a four-spoked wheel with a diameter of 150 m. if the space station rotates at a rate of 2.45 revolutions per minute, what is the magnitude of the artificial gravitational acceleration provided to a space tourist walking on the inner wall of the station?
