A uniform rod BC with length a is attached to a light string AC. End A of the string is fixed to the ceiling and the end B of the rod is on a smooth horizontal surface. B is exactly below point A and length AB is b (a lt b lt 2a). The system isreleased from rest and the rod begins to slide. Find the speed of the centre of the rod when the string becomes vertical.

1.	A uniform rod BC with length a is attached to a light string AC. End A of the string is fixed to the ceiling and the end B of the rod is on a smooth horizontal surface. B is exactly below point A and length AB is b (a lt b lt 2a). The system isreleased from rest and the rod begins to slide. Find the speed of the centre of the rod when the string becomes vertical.
Answer» ANSWER :`V = SQRT((s(a-(B)/(2)))`
