Two particles A and B are connected by a string of length 2L, intitally the system is kept at rest on a smooth horizontal table and particle B is a distance L away from particle A. Particle B is imparted a velocity 'u' perpendicular to the line joining AB. What is the velocity of A just after the string becomes taut?
