Question

A smooth sphere A is moving on a frictionless horizontal
plane with angular speed ⍵ and centre of mass velocity v. It
collides elastically and head on with an identical sphere B
at rest. Neglect friction everywhere. After the collision, their
angular speeds are ⍵A and ⍵B, respectively. Then
(a) ⍵A< ⍵B (b) ⍵A= ⍵B
(c) ⍵A= ⍵ (d) ⍵B= ⍵
