Two identical balls $P$ and $Q$ moving in the $x-y$ plane collide at the origin $(x=0,y=0)$ of the coordinate system. Their velocity components just before the moment of impact were, for ball $P$, $v_x=6\ m/s$, $v_y=0$; for ball $Q$, $v_x=-5\ m/s$, $v_y=2\ m/s$. As a result of the collision, the ball $P$ comes to rest. The velocity components of the ball $Q$ just after collision will be
