You'll need to know two things: the weight of the projectile, and its velocity at the muzzle.
Here's a handy dandy calculator-

Basically, at under 1 Joule, we're talking about airsoft guns; and there's a dedicated forum right next door-
Sports > Airsoft & Paintball

Have you any idea how i can find out the speed, i know it fires 5.5gram pellets. Thanks

Well, ideally you'd measure it with a chronograph, but airgun manufacturers usually state the muzzle velocity of their guns in the literature.
What make and model are you talking about?

Also, are you sure about the "5.5gram pellets" bit?
That'd be about 85 grains, which is the weight of a middling size rifle bullet.

so to stay under 1 joule the round would travel at 62.5 feet per second.

You'd be better off throwing it i'd say

That's what I was thinking too

I suspect the OP meant 5.5gr (grains), which would be about 0.35g (grams).
Proper lead airgun pellets seem to be around 7-8gr in .177, and 14-16gr in .22, so I'm guessing we're talking about an airsoft of some sort here.

0.35g would be at the heavy end of airsoft BBs, probably 8mm.
I have no idea if any 8mm airsoft guns come in under the 1 Joule limit, that's a question for the Airsoft & Paintball forum.

5.5mm is the diameter of the pellet, and therefore is also (nominally) the calibre of the gun.
.22 pellets are conventionally referred to as '5.5mm', even though 0.22" = 5.588mm.
See here- http://www.eley.co.uk/airgun.htm

Anyhow, it sounds like you're looking at a .22 airgun, and as far as I know, all conventional airguns generate plenty more muzzle energy than the 1 Joule limit.

Can you just do that ??

Garda: So do you have the letter, including the serial number, from the Dealer where you are buying the firearm.

Mr. Soap: No I bought it years ago I've just been holding onto it illegaly at home, I almost got caught with it the other day so I said, I'd better licence it ... but I have the serial number written down here!

Garda: ???
