A projected space station consists of a circular tube that will rotate about its center (like a tubular bicycle tire) as shown in the figure . The circle formed by the tube has a diameter of about 1.1-km
What must be the rotation speed (revolutions per day) if an effect equal to gravity at the surface of the Earth (1.0-g is to be felt?
Please help. I do not even know where to start.
Physics Gravity -
g = R w^2 = 9,8 m/s^2
R = 550 m
Solve for the angular velocity w in radians/second
Then convert that to revolutions per day.
