Dynamics angular velocity question

    [SOLVED] dynamics angular velocity question

    I've tried this problem with a simple way of kinetic energy and potential, but I am now where close to the answer of 11.1. There must be a way of doing it I don't know of.

    The .1 kg slender bar and .2 kg cylindrical disk are released from rest with the bar horizontal. The disk rolls on the curved surface. What is the angular velocity when the bar is vertical. The radius of the disk is 40 mm. and the length of the bar is 120 mm.

    A quick drawing of it is attahced.
