Two billiard balls of equal mass tb8le(vw-y;9b(wk)k-gneqr move at right angles and meet at the ord l(:d4as pb0bigin of an xy coordinate system. Ball A is moving upward along the y axis at 2m/s and ball B is moving to the right along the x axis with speed 3.7m/s After the collision, assumed elastic, ball B is moving along the positive y axis (Fig. 7–37). What is the final direction of ball A and what are their two4b:s d0pb(al d speeds? direction of ball A is  ----待选择----x directionx direction v'$_A$ =    m/s v'$_B$ =    m/s
