Then begone troll. i banish thee to my ignore list. There's no point in trying to converse with someone whose only arguments are cut from another web site and who lies about what evidence they know.
the rock analysis was all my own. I overanalyzed it on purpose to expose the absurdity of it all.
I thought my little physics lesson was pretty good. if there was a way to establish some kind of minimum velocity of impact for the 10 lb rock to shatter the glass then you probably could work your way back using Newton's law of motion to calculate how far away from the house he needed to be be, the angle of the throw, and the velocity of his throw, but there are probably two many unknowns and too few equations. it's been a long time since I have solved for these types of variables in standard projectile motion problems. if somehow you were able to get some numbers for these variables then maybe you could survey the yard to see if the constraints of the yard and the house could have allowed for the distance, velocity and throwing angle that you calculated and if not then it wasn't done and we could rule out the rock throw from the outside. actually, you probably would just assume a throwing velocity, like 100 mph for Rudy, 3 mph for wimpy Raffe, that seems reasonable based on what a human could do, so then you could determine the angle of the throw and the distance thrown.
I think it's better to resolve big picture problems first before getting down on the weeds on stuff like could the 10 lb rock have been thrown up there and broken the window. first we need to establish anybody even climbed up there b/c it doesn't matter if the rock was thrown from the outside if nobody ever made the climb up to and thru the window.
