a) An event, E1, has spacetime coordinates (x, t) = (120 m, 20.0 s) in reference frame S.

Reference frame S' moves at 0.600 c in the +x direction with respect to S. Assume that events with coordinates (x, t) = (0, 0) in frame S have coordinates (x', t') = (0, 0) in frame S'.

Calculate the spacetime coordinates of event E1 in the frame S'.

b)The event, E1, has spacetime coordinates (x, t) = (120 m, 20.0s) in reference frame S. Reference frame S' moves at 0.600 c in the +x direction with respect to S.
