plz help im stuck

Two inertial frames S and S' are in the standard figuration. As measured in the S frame, S' has velocity V = 0.6c along the positive r-direction. An event occurs at s' = 40m, y = = = 0m. 1 = 2 x 10 $ s in S'. a) What are the spacetime coordinates of the 8 b) Another event occurs and the observer in loulates that the spacetime separation between the two events in their frame is (A. . 230 m Are the two events causally related? Explain your answer. (2) c) What is the spacetime separation between the two events as described in (b) in frame S? (1) [11]
