1. The problem statement, all variables and given/known data An object moves at v=0.94c in the frame of a laboratory for 32 us, decaying as it reached the other end. a) how far did it move in the frame of the laboratory? b) how long did the object travel in its rest frame? c) in the rest frame, how long is the laboratory? 2. Relevant equations t' = gamma * (-v/c^2*x + t) x' = gamma* (x-vt) 3. The attempt at a solution for a, I did: x=v*t = (0.94c)(32us) =90,177.6 m b) t' = gamma * (-v/c^2 * x + t) = 10.9us c) x' = gamma * (x - vt) = 0 m thanks!!
