tp gun

[Rubber314Chicken]

does anybody have any ideas on how to build a gun/catapult that would launch tp about 40 feet into the air?

 

[joxley1990]

Lots of wood, elastic bands.. etc, what do you have?

 

[Rubber314Chicken]

about 20 feet of rubber, 1/16"x3/16" and a great deal of wood.

dont forget surgical rubber

here- anybody who knows physics- how many pounds of thrust would be required to launch a 1.5 pound projectile 45 feet into the air?

 

[borat_sagdiyev]

half life 2 will always tell you

and it depends on the density of the air and the size of the object and stuff.

 

[Rubber314Chicken]

a standard roll of tp- 5" in diameter x 4.5" long

assume sea level

you'de need to know mass...

 

[borat_sagdiyev]

yeah mass is where its at lol. theres a difference between mass and weight ya know...

 

[hascet]

Ya, physics is hard...lol lots of different equations! weight is the force of gravity on something which is Fg=weight=9.8N(mass)...complicated i know I have a final on it next week
