Textbook Question

Chapter 7, Problem 31ICA

A body traveling in a circle experiences an acceleration (a) of a = v²/r, where v is the velocity of the body and r is the radius of the circle. We are tasked with designing a large centrifuge to allow astronauts to experience a high "g" forces similar to those encountered on takeoff. One "g" is defined as 9.8 meters per second squared [ml²]. Design specifications indicate that our design must create at least 5 "g''s. If we use a radius of 30 feet [ft], what is the required velocity of the rotating capsule at the end of the arm, in units of meters per second [m/s]?
