A space station is designed in the shape of a large hollow donut that is uniformly rotating the outer radius of the station is 560 m. With what period Must the station rotate so that a person sitting on the outer wall experiences an acceleration of 9.8 m/s?

Solution
a = ²r = ² * 560m = 9.8m/s²
  = sqrt(9.8m/s² /560m) = 0.1323 rad/s
 T = 2 /  = 47.5 s
