Gave us:

snooker then. the whit ball is substantially smaller than the others,
"and yet it moves" (to paraphrase gallileo)


Substantially?

No. Try 2" cue ball or "white ball" and 1.875" object balls.

Again, you dopes are moving toward the striking object being bigger
than the struck object, which is NOT the case in this debate.

Be less dopey, and get back on track with some scenarios that
approach the debated case.

Like the .22 hitting the bowling ball.


OK, a .22 long rifle hitting a bowling ball. What velocity will it
impart to the ball? To make it simple, assume the ball slides, not
rolls.


*** that. I said .22 short, which MIGHT more closely resemble the
force we could muster.

Also, place it in space at even a quarter mile away.

First, we need the velocity of the .22 projectile, which is
dependent on slug weight, powder load, and barrel length, as well as
the type of powder, and now we need to put OXY in the cartridge as
space and gunpowder burning do not go together.

ONCE we have the muzzle velocity of the projectile, we can assume it
to be constant as there would be no atmospheric pressure front upon it
in space.

So mass of projectile, and velocity. We should also decide if we
want a round projectile, and whether it should be hard or mutable.

Then, we need to determine where and how we are going to impact the
spheroid, and whether it is tumbling as would be likely or a
stationary jaunt through the heavens.

Then, we need to know the size and weight of the spheroid (bowling
ball), its modulus of elasticity, or we can make it brittle.

There could easily be a few more factors

THEN, one can do some calculations.
