1. The problem statement, all variables and given/known data 2. Relevant equations dont think need any equation 3. The attempt at a solution a) i said that if the lightning is simultaneous in rocket frame, then the pilot is in the rockets frame there the rockets frame is the pilots frame therefore the pilot sees it simultaneously. correct? b) not sure how to approach it. help edit: think i know here goes: i used Lorentz transformation, the trees are at equal distance a part(rocket frame. lets say tree1(x1) is to the left then tree2(x2) is to the right. i let both t1 wrt tree1 and t2 wrt tree2 be the same b/c t1=t2 because happens at the same time for rocket. then transforming i get t'1=t'2. there student at rest sees as a simultaneous event.
