1. The problem statement, all variables and given/known data How fast must the observer be moving in the +x-axis direction so that events A and B occur simultaneously? 2. Relevant equations I am currently in the solving stage of this problem and I need some help factoring this out/entering it into Octave. Can anyone help? 3. The attempt at a solution I am currently nearing the end of the (*hopefully) working solution. I am currently here: 1.296e33=v^2(9e16-v^2) How do I solve from here either by hand, or by entering it into MATLAB/Octave? I appreciate all help! Thank you very much for your time.
