Attaching the image of the problem as an image. Somehow text is not copied from the book.

Somehow, I can't imagine the picture in my head. We can do it in 2D plane. I know, it mentions the solution, but need to see the drawing, otherwise, my logic fails.

I thought that maybe, first half space where we got ##U_1## constant, we draw it in ##x<=0## and 2nd half space when ##x>0## and I guess we treat instanteneous movement from first to second half space. I get it that since ##x=0## still belongs to first half space, on the whole ##y## axis, potential energy doesn't change and still is ##U_1##. But when particle moves into 2nd one, definitely, force would act on ##y## direction, making momentum change.

Would appreciate if you could draw a picture of where angles are, half spaces, normal and so on.
