A space station is a ring of radius 250 m. To produce artificial gravity of 9.8 m/s^2 at the rim, it must rotate at:

  1. 0.099 rad/s
  2. 0.0392 rad/s
  3. 0.198 rad/s
  4. 0.396 rad/s
Answer

C) 0.198 rad/s

romega^2 = g Rightarrow omega = g/r = 9.8/250 = 0.198 rad/s. SLO P-11-B-17 · Understanding
