The intitial velocity limitation says 'vertical'. I don't care what
size the 'walnut' is, it will be impacted given there was no
horizontal velocity component.

There is always a horizontal component, although one isn't really necessary.

Even if there was, by the way, the Newtonian physics demand the path
will cross the starting point, and the implication to most readers
would be that was on a surface.

If there's a surface in the way, the starting point and ending point will be
different.

Care to write an equation or two to demonstrate that? It's a two body
problem, one massive with respect to the other. The initial conditions
are a vertical impulse from the surface, of a massive sphere. That's
high school physics.

You need an equation?

I throw a baseball into the air. It lands twenty feet away. The starting
point and ending point are different.

I finished high school a long time ago.

Read the post -- it specified vertical. It may be your concept of
vertical is different than the one commonly accepted. If your throw
was vertical you had aerodynamic effects, disallowed earlier in your
earlier post.

I would have suspected you did finish high school some time ago. That
you have forgotten what you learned is obvious.

You would miss.

Maybe more viagra to make him taller would help?
