Is it possible to know both the y-coordinate and the momentum in the x-direction at the same time?

(I know that you can not know the x-coordinate and the momentum in the x-direction, but I'm not sure about y-coordinate)

Yes, because those operators commute.
 
Yes you can.
 
ok that's what, just want to check...thanks
