Re: What I don't understand.

In Response To: Re: What I don't understand. (SiliconDream=PN=) Here's the real kicker. Since you have negated the missile's tangential velocity, and then added enough of a Y direction (radial) velocity to get it to the center, it will continue straight upwards, towards the other side opposite side of the ring, but only to a non-rotating observer. The person sitting on the ring who just fired the missile would be surprised (depending on what the Missile's initial radial velocity - radial escape velocity of the ring = average net radial velocity actually is) to see the missile totally miss its intended target. By counteracting the spin of the ring completely, and then aiming the rocket launcher accordingly, it becomes virtually impossible to hit your intended target. The added difficulty becomes is that a trajectory must now be calculated involving the rotation of the ring, and the time it takes for the missile to traverse the diameter of the ring. The initial radial velocity of the object must be calculated precisely so that it will reach the opposite side of the ring when the correct portion of the ring is underneath. Or, one can adjust the initial launch vector accordingly and fire missile on a more direct path to the exact point where the target will be in however many minutes. On another note, I also did a fairly simple algebraic derivation and ended up with -vi^2/g=2d=16000000m (this assumes the target distance to be exactly the radius and the final velocity to be 0, which it would be at that distance). Now, as others have pointed out, g is almost impossible to calculate, so vi is too. However, what this does show us, is that g is miniscule in comparison to vi, no matter what vi really is. The fact of the matter, is that there is gravity pulling from the other portions of the ring, so haowever massive or dense the ring is, it is (assuming a fairly uniform ring) counteracted by the rest of the ring. Just an interesting tid bit, eh? Gravity will never interfere that much, but one still must account for the Lagrange point in the middle of the ring. The missle, if fired at only the necessary radial escape velocity, would get stuck there. You need an extra push to get it just past the center. This isnt crucial, but since people were debating missile trajectories, I felt it would be important to bring this up. It would be hilarious if u were on the other side of the ring when the missile hit, and it killed u instead of ur enemy. .:Magh Tuireadh
