If rod BD is fixed at collar C, it is not rotating, correct? Why is the angular acceleration being asked if it's not rotating?
Angular acceleration without rotation?

It's not fixed at collar C, it's sliding through it. It if were fixed, there would be 0 degrees of freedom, and OB could not be rotating.

it also looks like the collar can rotate at point C

This is also a kinematics problem, not an introductory physics problem, and involves using relative velocities.

Nevermind, it is rotating. Thanks!
