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)=6m//s, v_(y)=0,p` for ball `Q, v_(x)=-5m//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:
