Would you like to show me such with this example please
A 100 gram ball is shot from inside a 1000 gram box.
The box is 10 cubic yards long and of course
all vacuum around and inside.

10 cubic yards long? Cubic yards are a measure of volume,
not length.

The ball is shot using an acceleration rate of 1 meter per
second/second.

For how much time is the ball accelerated? (This is
necessary to determine how fast the ball will be moving
when it strikes the far wall).

Also, is the mechanism that accelerating the ball
anchored to the box?

Please do show what happens when the ball hits the
other side
of the box and of course, don't forget to include the box moving
because of the shooting of the ball from the "at rest" state of
both the ball and the box.
I would really love to see the Kinetetic energy transference
you come up with that will show the ball will stop the box
from hitting the wall.

Why don't you have a go at it yourself, then we can all
compare notes?
