= An observer at origin of inertial frame S sees a flashbulb go off at x = 190km, y 20km, and z = 0km at time t = 5 x 10-4s. At what time and position in the S' system did the flash occur, if S' is moving along shared x-direction with S at a velocity v = 0.8c? Let the origins of frame S and frame S' coincide at time t = 0 and t'= 0. Hint The time (in units of 10-4s) and position (in units of km) of the flash is [Format hint: Specify your answer as a 4-tuple, for example, (2, 100, 5, 1), for a flash occurring at 2 x 10-s at the location of (x = 100km, y = 5km, z = 1km).]
