What must be the period of rotation of a spatial station so that artificial gravity in a cabin that is 45 m of radius from the axis of ration corresponds to gravitational field at the surface of Earth ?
Sum of forces r prime = (mv^2)/r
The Attempt at a Solution
I think that I have the following two forces : normal and gravitational force.
After that I don't know what to do. The situation is btw a circle.
