A space station is shaped like a ring and rotates to simulate gravity. If the radius of the space station is 140 m, at what frequency must it rotate so that it simulates Earth's gravity?
Require that R w^2 = g
w is the angular velocity in radians per second and R is the radius. Solve for w.
Divide w by 2 pi to get revolutions per second.
