First of all we need to convert everything into SI units.
Let's start with the initial angular speed,
. Keeping in mind that
we have
And we should also convert the angle covered by the centrifuge:
This is the angle covered by the centrifuge before it stops, so its final angular speed is
.
To solve the problem we can use the equivalent of
of an uniformly accelerated motion but for a rotational motion. It will be
And by substituting the numbers, we can find the value of
, the angular acceleration:
