Two particles A and B of equal mass m are attached by a string of length 2l and initially placed over a smooth horizontal table in the position shown in Fig. Particle Q is projected across the table with speed u perpendicular to the line joining them. Find the velocities of each particle Q after the string becomes taut and the will be.

Two small particles of equal masses start moving in opposite directions from a point A in a horizontal circular orbit. Their tangential velocities are v and 2v respectively, as shown in the figure. Between collisions, the particles move with constant speeds. After making how many elastic collisions, other than that at A, these two particles will again reach the point A?
