Ok, I know what the problem is, I made a mistake in the moment of inertia...

I do have another question due.

First of all, when they say this is the angular acceleration of the poll, does it mean the angular acceleration of the center of mass?

In the next part of the question, they ask for the angular velocity as a function of $\displaystyle \varphi$.

I tried to use energy conservation and came up with this equation:

$\displaystyle mgL=mgL(1-1/2\cos(\varphi))+1/2 mv^2+1/2 I\omega^2$

When

$\displaystyle v = \omega*(L/2)$

Is this right?
