## Homework Statement

A centrifuge is a laboratory device used for spinning samples of material. In a blood centrifuge, a test tube is inserted at an angle

*θ*=32.0° with respect to the vertical and the whole sample is spun at high speed. For a typical test that is l= 15.9 cm long and is spun in a centrifuge at a rate of 4316 rotations per minute, what is the centripetal acceleration experienced by the sample at a point

*x*=9.93 cm from the rotation axis, as measured along the test tube? Express your answer in units of the standard gravity

*g*. Thus, if your answer is 19.62 m/s2 = 2.00×9.81 m/s2, you would enter 2.00 into the box.

## Homework Equations

a=v

^{2}/r

T=2πr/f

v=d/t

## The Attempt at a Solution

First, I found the period

T=2π(15.9)/(4316/60)=1.3888

v=2π(9.93)/1.3888=71.9

a=(71.9)

^{2}/9.93

I don't think I did this correctly, as I didnt use the angle...
