PS... I know this forum is not for new theories so I will not post it here but any ideas where I can go to put my theory out there? It actually is regarding general relativity and Time Dilation.

Yeah and that was one of my fears when seeing the quadratic equations because given my problem that I put in place I could only have one correct answer so I shunned the quadratic equasion. I just forgot that since the Person B is traveling in a straight line that and that pusing the numbers...

It makes sense but Pothag theorem can be expanded in three dimentions by D^2 = A^2 + B^2 + C^2 where D is the Hypotenuse. Your way works too!

Well... I ran into another issue. The following formula makes sense but i question it's usefulness or accuracy. Mainly because i can get two answers when there can only be one... (CT)^2 = (Dx + (VxT))^2 + (Dy+ (VyT))^2 + (Dz + (VzT))^2 Standard P. Theorem for a 3d triangle. Now we...

After reading this whole thread through light bulbs are going off! this might be what I am missing. The sad thing is that it would have been so simple... but such is life and that it what an extra set of eyes are for!

I do see what you are saying. This would normally work if the paths made a right triangle. Then using pythagorean theorem that would make things easier.

Please let me know how I can make it clearer. I was trying to say that the source of sound is at (0,0,0) and person b was 10 units away from that point on the X axis. You can make a formula to get the C components but you still cannot solve for the correct set without knowing the total time...

Granted. Eventually you will need to compare C (speed of sound) with V (velocity of the person). To do this you will need to break down both into the three components. V is already done with (1,1,1). How do you properly breakdown C into its three components without knowing how much time it...

Ok doing that I get: Di / (Sos - Vop) = T What next?

Given the example I can start with: (radius)/speed of sound. = (distance walked)/speed of person b (Initial distance + distance walked)/SOS = (distance walked)/ SOP (Di + (SOP * T)/SOS = (SOP * T) /SOP This just looks like its going to just cancel out or something...

Yeah, I got that part about a sphere. My problem is I have two (at least) unknowns . How do I solve for that? The time it takes to intersect and the breakdown of the sound wave into its three coords so I can add the velocities... Any thoughts? I have been trying to rip this apart and feel...

I have a scenario that is driving me crazy and I am hoping someone can help. My setup: Person A is at coords (0u,0u,0u) Person B is at coords (10u,0u,0u) Person A has a bell and at the same time he rings it Person B moves with a velocity of (1u,1u,1u) At this point Person B has not...

Thank you for that! I still do not seem to be getting a clear cut answer. What I am striving for a formula that i can use for this and just plug in the following: initial (x,y,z) of person 1 initial (x,y,z) of person 2 (x,y,z) Velocity of person 1 Overall Velocity of person 2 I want to...

can someone double check me? I got T = 6.25 which means Person 1 (from 0,0,0) traveled a total of 23.38125m and Person 2 traveled 25m.. Sounds close but does not feel right...

Ok i got that far... Can you show this because I can't seem to get there... I get this: 13t^2-20t + 100 = 16t^2 guess I am looking for the next step... I can get it down to: t^2 - (20/3)t = (100/3) (I kept it as fraction to keep it clean) ideas? I know it is something simple
