It has been suggested that rotating cylinders about 8.0 mi long and 3.5 mi in diameter be placed in space and used as colonies. What angular speed must such a cylinder have so that the centripetal acceleration at its surface equals the free-fall acceleration on Earth?

---------rad/s

-
a=w^2r
so w=(g/r)^1/2
=0.059 rad/s
