Well I did an experiment using an air cannon to find the drag exhibited on a cylindrical projectile using different mass/density and pressure/velocity. However, I was not able to obtain light gates at the time, so now I have no measurement for velocity. This is necessary for my results, and I was wondering if anyone could help me in calculating it. I have all dimensions and volumes of the components to the air cannon and projectile, distance and time of flight of the projectile, air pressure within the gas chamber and launch angle.

If anyone could help me calculate the exit velocity of the projectile it would be greatly appreciated.

Yeah I want to finish my assignment already. Been wanting to do this since Friday...

high speed camera?

This is the problem, when we were experimenting, we could not obtain light gates, or a camera.

We were thinking of calculating mathematically. We know the psi at which the particle was fired.

should be pretty simple figuring out the speed and velocity of the projectile with he force (PSI) calculations

Yes simple, if you know the equations.
Which is what im kinda asking.

I guess cybergamer is full of dumb baiting idiots.

Getting more help from GotGames which has 3.5x less members than CG...

It's actually sort of cheating asking for help.

Hmm. thanks for the help anyway community.

lol if you're going to be a ****wit to the community before the people who actually know how to help you read your thread, good luck in getting help with anything.

What sage said
but srsly - if you have distance and time, that's all you need....

distance/time = speed

150m in 15 seconds

150/15=10metres per second...

"I have all dimensions and volumes of the components to the air cannon and projectile, distance and time of flight of the projectile"

Um is that a bait or...

If you actually read the first post, you will see that it says the exit velocity, not the average velocity. Nice try though...

yeah because cybergamer is the place to learn physics, good luck on your assignment.
