(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I am wondering what the speed of a projectile would be if it were launched with compressed air at 115 psi (approx. 800 kpa). The weight of the projectile is 4 grams. I have converted the weight to mass (please correct me if im wrong) which makes it 0.408 grams. The diametre of the outlet is 8mm.

Is there a way to figure this out without knowing the time taken?

2. Relevant equations

f = ma

where:

f = 40.2N

m = 0.408(unknown measurement)

pressure = force/area

3. The attempt at a solution

I have looked all over the internet for anwers to this question, yet couldn't find something helpful.

The force of the air is 40.2N.

The mass of the projectile is 0.408(i don't know what measurement to use...).

I have found the accelleration to be 98.529(i don't know what measurement it is...).

But I want to find the speed and not the accelleration. How do I get it to that, because I have looked on the internet through several threads and sites, but nothing has come up.
