The rigid structure rotates about axis AB with angular veloc

The rigid structure rotates about axis AB with angular velocity of 4 rad/s clockwise when viewed from A and angular acceleration of 10 rad/s^2 counterclockwise when viewed from A. Find the velocity and acceleration of point C, expressed as vectors in terms of unit vectors I, j, and k.

Solution

v=r*w here w is angular velocity

a= mv2/r =mrw²

Angular Acceleration is the rate of change of angular Velocity with respect to time. It is a vector quantity.
