It has been suggested that rotating cylinders about 9 mi long and 5.1 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?

    please omit this question, I have solved it on my own. THANKS!!!

    w=sqrt(g/r)
    r=d/2
    r=5.1/2
    r=2.55
    r=4103.8272
    w=sqrt(9.8/4103.8272)
    w=0.0488673180 rad/s
