So the pellets still have a lot of travel left before they lose all speed. My boat got shot at about 100 yards. I was chasing a cripple and the blind next to me had no idea I was there. The pellets plinked pretty hard off my aluminum boat.![]()
I don't know how accurate this is. Seems a little far but not wildly more than my understanding under ideal conditions.

Think of the furthest away you have had shot rain on you. It's a long ways for me.
I never got to the point of adding in drag.SpinnerMan wrote:You didn't include drag.
Your calculations are for shooting in a vacuum. We aren't talking about NASA astronauts shooting on the moonYou need account for the pellets slowing down because of wind resistance. What is the wind speed and is it a head wind or tail wind? How long does it take a pellet to go from 1500 fps to 0 fps? The drag coefficient, the ballistic coefficient which I don't understand that go into more complex equations that I don't understand.
Just be glad they aren't going so fast that you have to include relativistic effects. However, that I could actually explain.
or written in the form that you are more familiar.

His son was on my Little League team. At the beginning of our senior year physics. He gave us a problem and said if we solved it, we'd get an A for the year. I took it home and solved it and gave it back to himI never asked and he never said a word about it, so I knew it was right and also that he couldn't give me an A for the year
7 years later when my youngest brother took his class, he told them only one student had ever solved this problem
I was a nerd, I really loved that shit.
I definitely know the ideal gas law off the top of my head. PV=nRT. I also know a fair bit about non-ideal gases such as our atmosphere. Most know of my nuclear education, but I also studied a lot of environmental engineering so I have a lot of useless knowledge on atmospheric physics. PV=nRT is just the starting point like your Newton's equations of motions are the foundation that requires correcting for things that don't behave as ideal gases or like they are in a vacuum.
