I don't really understand what a G-force is and how it can be used to solve problems using the formula: $$T=mv^2/r$$
T is tension, m is mass (in kg), v is velocity (m/s) and r is radius of the circle.
The question is as follows: To withstand g-forces of up to 10 g's pilots train on a human centrifuge. In a human centrifuge, if the length of its arm is 12 m. what speed is the rider moving when he experiences 10g/s?
Now assume that an individual experiences 14g's, where the centrifuge is rotating at 1 rev/s. How long will the centrifuge arm be?
Its not clear to me what exactly is the unit if a "g" and whether g/s is a speed or not. Any help here would be greatly appreciated
