A solid sphere is rolling without slipping (w,v) on rough ground. It collides elastically with an another identical sphere at rest ther is no friction b/w the spheres. radius of each sphere is R and mass m. What is the net angular impulse imparted to the second sphere during collision

i think the ans is zero because due to elastic collision only linear velocity of 1st sphere is changed to zero but as there is no friction between the spheres the angular velocity of 1st sphere remains the same and the 2nd sphere only follows translational motion

the answer is not zero. There is no friction b/w the spheres but the ground is rough due to this there exists certain angular impulse
