My Rocket Challenges Your Fastest Projectile! Even Some of Your PB's!

(Hold my beer while I warm up my slide rule...) What is the weight of the person slugged by Chuck? How far does away does he land?

80 kg weight and landed 7 km away. But the trajectory was a high arc, while cartwheeling, so the actual distance traveled is further.

The equation you need is a=(1/2 x V^2)/s

Where a= acceleration in ft/sec^2
V = muzzle velocity (feet/sec)
s = barrel length (feet)

Example:. my R9 with a 16 inch barrel has a MV of 900 fps with a certain pellet

a = (1/2 x 900 x 900) / 1.333 feet = 304,510 ft/sec^2 or 9,460 g's

Hope this helps

That will only give the average acceleration, the peak will be much higher depending on the gas flow into the barrel. The peak will have a very low duration.

A springer simulation for a 12FPE springer suggested a peak acceleration of around 22,000 g's.

You can still get fireworks here, though it will probably be banned soon.

Not that long ago you could also buy a rocket with like 5-600 grams of load, today the max are 79 grams
Anyway, amateur rocketry, like even the smallest Estes A motor,,,,,, never been legal here

The load change, well happened after a fireworks warehouse,,, intelligently put in a residential area blew up..

Do you live in North Korea?

Do you live in North Korea?

No Denmark, but it is a place that do like flirting with socialist core values, and i have to admit compared to the old socialist / communist states of history, well we got them beaten on most fronts, actually it is a bit scary to realize..
And to top it off we are in the inner most group of Americans very best friends,,,,,, though here i do think they are just stringing us along as useful fools.

I do use GPS as well as a doppler radio tracker. When flying above 5000', you are above the "surface winds" and the winds up there can be 90 or 180 degrees shifted. I had my girlfriend with me at one launch and we were trying to track the 3" Exocet that just went to 9000' feet. The location on the GPS app showed a spot I swore was impossible, and that it was just showing the nearest cell tower (its backup method for location). She kept telling me to go there and I kept telling her to stop being stupid. EVERY SINGLE rocket drifted to the southwest that day and that's where I was trying to find it. We gave up after an hour and drove back to the launch site. There was a squad car there and a female cop was pulling my rocket out of the back seat! It had landed exactly where the GPS showed, of course. One mile due EAST in someone's front yard.
