(a)Determine its rotational kinetic energy at this point? J

(b) Determine its translational kinetic energy at this point? J

*v=wR --(2)*

The problem i feel confused is that what is R for since part of the wheel is inside the groove. I am not sure the question is just simply sub (2) into (1) and find the answer.
