HW8 #8

Is this question referring to the initial speed of the point or after the time interval given in #5?

The wheel starts from rest. #8 is referring to the speed after the time interval given in #5.

Thank you!
I am also unsure about what equation applies to this particular problem. I've been looking through my class notes for hours, but I can't seem to find a formula that incorporates the distance from the axis of rotation.

In #5 you found the angular velocity ω of a point on the wheel. the linear velocity (speed) is related by v=ωr. That's an important relationship.
Good luck.
