It won't be a waste of time if i learn something new. Like a failed experiment isn't a waste of time because you learn a new way NOT to do something. I also view things like an unsolved equation. If one way to solve an equation doesn't work try another way till it does. Thanks for the advice...

ok thanks, I'll be sure to check it out then.

wow thanks for the detailed reply. it is quite a push. 981 meters per second is a bit over 2100 miles per hour or 3300 km per hour. Is there an equation to calculate the resistance from the friction of the materials used?

Thanks for the reply. I'm new to physics so any help is much appreciated. Do you know of any sites that i can learn about the Conservation of Momentum" other than Wikipedia? Perhaps a more trust worthy web page?

thank you your answer hit my question square on. I'd like to ad another question if i may. If the tube is pointing straight up, is a vacuum just like before, would the change in atmospheric pressure effect the driving force behind the ball as it reaches further and further up? In my mind it...

the device i described is not a device at all but rather a representation of space, Earth's atmospheric pressure, launch tube, and a vessel. I should have been more clear on what was what. the cube represents space. the tube is a elevator like structure that reaches into space from...

There is a metal cube that is any size desired. the contents of the cube is a vacuum of space. there is a tube that is also a vacuum of space that also can be any size desired. The third item is a ball that fits air tight in the tube perfectly at the furthest point from the ball. The ball can...
