A space station shaped like a giant wheel has a radius of 114m and, when empty, a moment of inertia of 5.84E+8kgm^2. A crew of 163 are living on the rim, and the station's rotation causes the crew to experience an acceleration of 1.00g. 0 When 134 people move to the center of the station for a meeting, the angular speed changes. What acceleration is experienced by the people remaining at the rim? Assume that the average mass of each inhabitant is 64.9kg.
