That's the answer I got. Is that what the book gives?

Yes, thank you SO MUCH for all your help! I really appreciate all of this!

You're welcome. Sorry for the initial confusion.

Just remember that $KE_{rot}=\frac{1}{2}I\omega^2$ and $v=r\omega$.

Just for future reference you have to be careful because the relationship $v=r\omega$ assumes the object is not slipping.

Oh okay. What I really didn't understand about this problem that confused me is the fact that the disk was rolling up a hill. I still cannot picture that happening on its own lol.
