Problem: The 20G Centrifuge of NASA at its Ames Research Center has a radius of 29 feet and can create an artificial gravity on a person in the device up to twenty times of the actual weight of the person.
Part A: What is its spinning speed in term of revolutions per minute (rpm) when producing the maximum artificial gravity?
I need help to find its spinning speed in term of revolutions per minute.
