A sphere \( A \) moving with speed \( u \) and rotating with an angular velocity \( \omega \) makes a head-on elastic collision with an
\( \mathrm{P} \) identical stationary sphere \( B \). There is no friction between

W the surfaces of \( A \) and \( B \). Choose the correct alternative(s). Disregard gravity.
(1) A will stop moving but continue to rotate with an angular velocity \( \omega \).
(2) \( A \) will come to rest and stop rotating.
(3) \( B \) will move with speed \( u \) without rotating.
(4) \( B \) will move with speed \( u \) and rotate with an angular velocity \( \omega \).
