What is acceleration of a point rotating at constant angular velocity? How to construct an acceleration vector?

The vector of acceleration is directed to the center of rotation, and is called therefore centripetal acceleration . Acceleration a of a point rotating on a circle at constant distance R from its center, depends on its angular velocity W and the radius R :                a =WR , or substituting the expression for W                 W=V/R  , we obtain a in terms of V and R :                  a=V/R.

Initial Values of Parameters Radius of circle (r) 3 m Angular velocity (w) 1.0 rad/sec
