Question

An observer in reference frame S notes that two events are separated in space by 200 m and in time by 0.81 s .

How fast must reference frame S be moving relative to S in order for an observer in S to detect the two events as occurring at the same location in space?

Express your answer using two significant figures.

Explanation / Answer

if an observer in another frame has to observe the same event, the velocity of S' should be = 200m / 0.81 x 10^-6 = 246.91 x 10^ 6 m/s
