You are designing a centrifuge to spin at a rate of 15,850 rev/min.

a) Calculate the maximum centripetal acceleration that a test-tube sample held in the centrifuge arm15.8 cm from the rotation axis must with stand.
m/s²

b) It takes 1 min, 13 s for the centrifuge to spin up to its maximum rateof revolution from rest. Calculate the magnitude of the tangential acceleration of the centrifuge while it is spinning up, assuming that the tangential acceleration is constant.
