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).

You should be able to find that out.

Not unless you specify it. It could, for example,
accelerate for only half the trip across the container.
Or it could accelerate for the whole trip. You need to
be precise in order to get precise answers.

Why would it do such,
I am not placing anything else in the box to slow it
down this time.
Why are you so reluctant to use what is stated?


There is only 10 yards of travel time minus the box motions distance.
To make it easier
You can make the Box 10 cubic meters on the inside instead if you
wish. so it will have 10 meters to travel minus the motion of the
box's distance from the small masses force upon the box to move.
The device the "shoots" the ball will be in a smaller box embedded
in the wall so it will have the entire 10 meters to travel.

So this box is somehow able to keep pushing on the ball
for the whole trip, and is anchored to the wall of the
container. Okay.

No,
the box only pushes when the ball is "shot".
Why are you now making even more incorrect statements
about what is happening?
You truly are showing your reluctance now.
:)


Now, one more thing. Is the stated acceleration with
respect to the little box attached to the container wall,
or with respect to the original rest frame prior to the
launch?

All motions should be considered from one frame
only and that frame should be a frame that could
detect motion, so it will not be in the box.
To find out if the box atually moves, you must look
outside the box.
Again it is pretty funny you can't grasp that simple
fact about finding out if a box is moving or not.


Also, would you consider changing the yards to meters to
keep all the units in the metric system for consistency?

Yes,
I actually stated that somewhere.
Make the box 10 cubic meters and place the firing
device for the ball in a smaller box embedded
into the wall that will shoot the ball so you will
have the entire 10 meters of motion minus the reverse motion
of the box.
