Chapter 5 Problem 8: BIO Ultracentrifuge You are working in a biology lab and learning to use a new ultracentrifuge for blood tests. The specifications for the centrifuge say that a red blood cell rotating in the ultracentrifuge moves at and has a radial acceleration of 150,000 g’s (that is, 150,000 times ). The radius of the centrifuge is 0.15 m. You wonder if this claim is correct. Support your answer with a calculation.
