A ring rotates about z axis as shown in ...

A ring rotates about z axis as shown in figure. The plane of rotation is xy. At a certain instant the acceleration of a particle P (shown in figure) on the ring is `(6hat(i)-8hat(j)) m//s^(2)`. Find the angular acceleration of the ring & the abgular velocity at that instant. Radius of the ring is 2m.
