A sphere A moving with a speed u and rotating with an angular velocity `omega`, makes a head-on elastic collision with an identical stationary sphere B. There is no friction between the surfaces of a and B. Disregard gravity.

Options

A. A will stop moving but continue to rotate with an angular velocity `omega`
B. A will come to rest and stop rotating
C. B will move with a speed u without rotating
D. B will move with a speed u and rotate with an angular velocity `omega`

Answer

A, C
