Difficult Physics Word Problem?
To analyze a blood sample, a research lab needs to produce a radial force of 450 N on the platelets in a blood sample. To do this they plan to use a centrifuge that has a radius 0.325 m for the test tube holder containing the blood. If an individual platelet has a mass of 4.57 e-5 kg, how fast must the centrifuge spin? (Find tangential velocity of the outer edge of the centrifuge).
B. Determine the period for one rotation for the centrifuge when it is processing a blood sample.
