(A) with a constant velocity v, while the disc started rotating counterclockwise with a constant angular acceleration (beta) (the initial angular velocity is equal to zero);

(B) with a constant acceleration (omega) (and the zero initial velocity), while the disc rotates counterclockwise with a constant angular velocity (omega)

I don't understand it - if the instantaneous axis of rotation always passes through the point of contact between ground and a disc, isn't it like trivial?

could some1 solve it pls?? its for my gf she will kill me if i don't solve it by the morning. (if she's reading this, go away)
