I just thought of the fact that I also don't know what the speed of P (v) is.. only that |v| is constant, but the angle and therefore its (x, y) are also unknown. damn :)

I have a planetary system with planets orbitting a central star (circular orbits). I want to shoot a projectile P in a straight line from planet A to B and need to calculate the angle or vector to shoot the projectile P. I know the straight line of the projectile is physically not correct, but...

Let me replace the question above by its essence: I have irregularly (and unpredicatbly) shaped objects. These objects are composed of square boxes with all the same mass m. The boxes are glued together to form the irregular object. Two examples: http://www.redarcher.net/examples.gif...

Hi, Imagine: a computer program like 2D Lego with only 1 type of block (a small square one) with which you can create constructions. Blocks can be placed on an invisible grid. There is gravity, and boxes can't fly, so you need to build any construction from the ground up. Boxes are always...

Hi Johnny, because my question remained unanswered for quite a while, I already found a method for solving this problem. And it is exactly as you summarize. In the meantime though, I found out that my problem is a bit more complex, you still need to rotate the cannon to that angle, which...

the drawing is a bit messed up, but i think the triangle i meant to show is clear enough

Hey, I like writing puzzle games, and normally i solve my physics programming challenges on my own, but this problem i have now reveiled itself to be quite a tough one. Even after involving my smarter friends :) Probably plain easy for motion physics adepts, but i forgot most of my fysics...
