circular motion

IIT JEE 2015 Guidance › Mechanics questions › circular motion

A ring rotates about its axis z which is perpendicular to its plane of roatation xy. At a certain instant the acceleration of the particle on the ring is {(6)i-(8)j}m/s2. find the angular acceleration of the ring and the angular velocity at that instant, the radius of the ring being 2m.

small hint: think of tang and normal acc....

For who want another hint:

Hey just try component of acc tangential to circle/R will give ang acc....

and component of acc normal be a_N,
ma_N=mv²/R....this will give v
