Question

a ring of radius a and having mass m is placed on a smooth horizontal surface two massless rigid rods AC and BC each of length a are attracted to diametrically opposite points of the ring as shown in figure a particle of mass m moving with velocity v and another particle of mass 2m moving with velocity v strikes simultaneously the end A and B respectively and stick to rod find the velocity of point B just after collision will be

Answer 1
