A smooth sphere A is moving on a frictionless horizontal plane with angular speed $ω$ and centre of mass is moving translationally with velocity 'v'. It collides elastically and head-on with an identical sphere B which is at rest. All surfaces are frictionless. After the collision, their angular speeds are $ω_{A}$ and $ω_{B}$ , respectively. Then,

Since the spheres are smooth- there will be no transfer of angular momentum from the sphere A to sphere B- The sphere A only transfers its linear velocity v to the sphere B and will continue to rotate with the same angular speed -x3C9-

Since the spheres are smooth, there will be no transfer of angular momentum from the sphere A to sphere B. The sphere A only transfers its linear velocity v to the sphere B and will continue to rotate with the same angular speed ω.

Since the spheres are smooth, there will be no transfer of angular momentum from the sphere $A$ to sphere $B$ . The sphere $A$ only transfers its linear velocity $v$ to the sphere $B$ and will continue to rotate with the same angular speed $ω$ .
