A ball ofmass m moving with velocity experiences a head on elastic collision with one of the spheres of as tationary rigid dumbbell as shown in figure-5.149. The mass of each sphere equals m`//`2, and the distance between them is l.Disregarding the size of the spheres, find the angular momentum of the dumbbell in the reference frame moving translationally and fixed to the centre of mass of the dumbbell.
