9:57 Part (b iv) Describing this part of the Problem
11:48 Part (b iv) Why is Angular Momentum Conserved?
13:16 Part (b iv) Initial Angular Momentum of the Rod System
13:34 Part (b iv) Initial Angular Momentum of the Clay
16:26 Part (b iv) Final Angular Momentum of the Whole System
17:41 Part (b iv) Final Moment of Inertia of the Whole System
19:07 Part (b iv) Back to Conservation of Angular Momentum
20:09 Part (b v)

Here is a Veritasium YouTube video that explains quite well the differences between parts (a) and (b) of this problem. In other words, how the clay lump that hits off center can have a smaller change in kinetic energy than when it hits at the center of mass.
