[4] A centrifuge is used to separate solid blood cells from liquid blood plasma. The solid cells collect on the walls of a chamber of radius re = 8 cm which is spinning 350 times per second. The moment of inertia of the centrifuge (including the blood) is I = 1.2 kg m. (a) What is the normal force exerted by the chamber wall on one gram of blood cells? (b) If the centrifuge is switched off it slows back to rest in 10 8 seconds. Through what angle did the centrifuge rotate during the time it took to come to a stop? (Assume constant a.) Chamber Axle
