an astronaut rotates at the end of a test machine whose arm has a length of 10.0m. if the acceleration she experiences must not exceed 5g (g=10m/s^2? what is the maximum number of revolutions per minute of the arm?

5g>v^2/r

and v=RPM*1min/60sec * radius

5g>RPM^2 * 1/3660 * r

solve for RPM

42.77 RPM
