Q. A uniform rod is lying on a horizontal table and it is hinged at one end. A body collides with the rod such that the collision is elastic then

I) Conservation of momentum is applicable
II) Conservation of angular momentum is applicable about hinged point
III) Conservation of mechanical energy is applicable
