1. The problem statement, all variables and given/known data Reference frame S' moves at speed v=0.94c in the +x direction with respect to reference frame S. The origins of S and S' overlap at t=t′=0. An object is stationary in S' at position x′ = 140 m . Part B What is the position of the object in S when the clock in S reads 1.3 μs according to the Lorentz transformation equations? 2. Relevant equations x=γ(x'+vt') 3. The attempt at a solution I got part A, the Galilean transformation, easily enough. That came out to be 506.6 m. I've been getting the Lorentz transformation wrong and am thinking I'm missing something simple. I used γ=1/√(1-v^2/c^2) and obtained γ=2.93. I then multiplied this by the Galilean transformation and got ~1485, but Mastering Physics is saying no.
