Question

If a cylindrical space station 300m in diameter is to spin about its central axis, at how many revolutions per minute rpm must it turn so that the outermost points have an acceleration equal to g?

Answer 1

g=w^2*r you know r. solve for w, in radians/sec. multipy that by 2PI and you have rev/sec, then multipy it by 60, and you have rpm

Answer 2

It's actually Radical g/r to get w. Then you DIVIDE by 2PI then multiply by 60.
