Question

You are working in a biology lab and learning to use a new ultracentrifuge for blood ts. The specifications for the centrifuge say that a red blood cell rotating in the ultracentrifuge moves at 470 m/s and has a radial acceleration of 150,000 g’s (that is, 150,000 times 9.8 m/s2). The radius of the centrifuge is 0.15 m. You wonder if this claim is correct.
What is the radial acceleration of the ultra-centrifuge using calculations ?

    Answer:

    The radial acceleration is  a_r = 1472667 \ m/s^2

    Explanation:

    From the question we are told that

          The velocity of the red blood cell is  v_r =  470 \ m/s

           The radial acceleration of the red blood cell is a_r =  150000g  =  150000*9.8 = 1470000 \ m/s^2

           The radius of the centrifuge is  r =  0.15 \ m

    Generally radial acceleration is  mathematically represented as

          a_r =  \frac{v^2}{r}

    substituting values

         a_r =  \frac{470^2}{0.15}

         a_r = 1472667 \ m/s^2
