Find out where an object is going to land

AI Thread Summary
The discussion revolves around calculating the landing position of an object in a 2D space after it is hit, using its position, velocity, and gravitational force. The user mentions that their current formula is yielding inaccurate results and expresses uncertainty about its effectiveness. They emphasize that time is not a factor since the calculations are updated every frame in a game context. A reference to projectile motion is provided as a potential source for the necessary formulas. The goal is to determine the x position where the object will land when y equals zero.

I have a formula at home that I tried but its not working to well so no use in posting it here. Anyway the idea is I have a 2d space and I hit an object. I have access to this objects position in space and velocity, also the gravity that acts upon this object. Time should not be a factor as I recalculate this every frame (its for a game). I am looking for the x position where it will land, while the y = 0;

If need be, I will post my formula from home later but again it gives me very inaccurate answers.

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
