A cylindrical space colony 13 km in diameter and 30 km long has been proposed as living quarters for future space explorers.Such a habitat would have cities,land,and lakes on the inside surface and air and clouds in the center.All this would be held in place by the rotation of the cylinder about the long axis.How fast would such a cylinder have to rotate at its perimeter to produce a 1-g gravitational field at the walls of the cylinder?
A) 200 m/s
B) 250 m/s
C) 650 m rad/s
D) 800 m rad/s
