# Centrifuge Acceleration#

The test tubes of high-speed centrifuges should be placed with care because of the very large acceleration.

## Part 1#

Assume the centrifuge is rotating at 3200.0 $$\rm{rpm}$$. Determine the acceleration at the end of a test tube that is placed 9 $$\rm{cm}$$ from the axis of rotation.

Please enter in a numeric value.

## Part 2#

If this centrifuge stops after 2.0 $$\rm{s}$$, what is its angular acceleration?
