A cart of mass has a pole on it from which a ball of mass  hangs from a thin string attached to point P. The cart and the ball have initial velocity . The cart crashes onto another cart of mass and sticks to it. The length of the string is . If the smallest initial velocity from which the ball can go in the circle around point P is , find the value of . (Neglect friction and take , )
