System Sʹ has a velocity u = +0.56c relative to system S, as shown in the figure. The clocks of S and Sʹ are synchronized at t = tʹ = 0 when the origins O and Oʹ coincide. An event is observed in both systems. The event takes place at x = 800 m and at time t = 3.0 μs as measured by an observer in S. What is the time tʹ of the event, measured by an observer in Sʹ?
A) 1.8 μs
B) -4.9 μs
C) 1.7 μs
D) 1.3 μs
E) 1.5 μs
