Passage-I : A rod AB length 2m and mass 2kg is lying on a smooth horizontal x-y plane with its centre at origin O as shown in figure. An impulse J of magnitude 10Ns is applied perpendicular to AB at end A. Find the coordinates of point A of the rod after time t=pi//45 of the impact if the centre of mass of the rod is taken as origin at that time.

1.	Passage-I : A rod AB length 2m and mass 2kg is lying on a smooth horizontal x-y plane with its centre at origin O as shown in figure. An impulse J of magnitude 10Ns is applied perpendicular to AB at end A. Find the coordinates of point A of the rod after time t=pi//45 of the impact if the centre of mass of the rod is taken as origin at that time.
Answer» `((SQRT(3))/(2)m,1/2m)` `((sqrt(3))/(2)m,1m)` `(3/4m,3/2m)` NONE of these ANSWER :A
