a_{com}=3g/4.I have calculated it from the radial and tangential components.
Is there another way of calculating it??

Yes , I have got the direction of acceleration of COM.I worked with radial and tangential components and found their resultant i.e a_{com} to make 30° with the tangential component .i.e vertically downwards .This showed that the net acceleration of COM was vertically downwards at the moment rod loses contact with the block .The net resultant force should be vertically downwards i.e -ve y-axis .Now N vanishes so horizontal component of Hinge force is zero .Have you got the direction of the acceleration of the COM?

So you discovered that it was about relation between polar and Cartesian coordinates? I did not want to confuse you by speaking about polar coordinates: :tongue2:ehild...Thank you very much ...
Its a fantastic experience learning from you .You taught me Physics ,Calculus,Polar Coordinates all in one question
