In particular I am only looking at part c. I know the simpler approach is to use energy. But I am thinking if i can do an integration of all the torque throughout the process, and hence find the integration of the net angular acceleration and find the resultant change in angular velocity. But I have no idea how to do the mathematics. Can anyone show me how the mathematics is done?

sorry but I still don't know how to go on from here! could you elaborate a bit further! In particular I was looking at using the 'infinitesimal' dτ or dα approach.
