A rotating space station has radius 1270 m, measured from the center of rotation to the outer deck where the crew lives. What should the period of rotation be if the crew is to feel that they weigh onehalf their Earth weight?
I got 101.1 seconds... is this correct? Please help!

w^2 r = g/2 = 4.9
w^2 = 4.9/1270
w = .0621 = 2 pi/T
T = 2 pi/.0621 = 101 seconds
