1.	A sphere A moving with a speed .U. and rotating with an angular velocity .omega. makes head - on elastic collision with an identical stationary sphere. There is no friction between the surfacces A and B neglect gravity(A) A will stop moving but continue to rotate with angular velocity .omega..(B) A will come to rest and stop rotating (C ) B will move with speed .U. without rotating (D) B will move with speed U and rotate with an angular velocity w.
