Posted by Anonymous on Thursday, October 22, 2009 at 2:33am.

It has been suggested that rotating cylinders about 12 mi long and 4.6 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?

    centripetal acceleation=w^2 * r

    r=2.3miles, change that to meters.

    set acceleration to g, and solve for w
