Know Y-Coordinate & Momentum in X-Direction?

[eit32]

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)

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

Yes, because those operators commute.

Yes you can.
