```							Dear Student,Since external force is absent here momentum will be conserved.Let m be their masses. Then,mv + 0 = mv1 + mv2v = v1 + v2..............(1) Since the collision is elastic, e = 11 = (v2 – v1)/vorv = v2 – v1.....................(2)Solving both the equations, we get2*v = 2*v2v2 = vand v1 = 0Hence, the solid shpehere will keep rolling with its inital speed v and second sphere will be at rest again even after collision.
