A rigid body is rotating around the vertical z axis anticlockwise when look at from above. It angular velocity decreases at a rate of 8π-2.
a) Calculate the velocity
b) Calculate the tangential and normal components of the acceleration?
c) Calculate the magnitude of the acceleration of the r=yj+zk point of the body when the magnitude of its angular velocity4πs-2! y=4cm, z=4cm.
