Angular velocity with time varying moment

[SteliosVas]

Hi there,

I have been given this question, and I have not even the slightest of clue's where to start.

I know angular velocity is equal to ω=v/r

But besides that I have no idea.

Where can I start?

How is it that you have been given a problem that you have no clue how to solve? Is this for a class?

Have you studied the terms 'moment of inertia', 'angular acceleration', or 'torque' yet?

Here are two clues:
1) You don't need mb.
2) You need to perform an integration.

Please note that I have changed the thread title to make it more descriptive of the subject matter. This is a requirement for the Homework sections of Physics Forums. The thread was moved here (because it is a homework type question) from a section where thread title requirements are not so stringent.

Ah right I got you guys, thanks for the help. It didn't click to me initially that if i integrate the momentum equation and multiply by 1/Inertia I should get the solution.

Thanks!
