    Relativety Problem

    A passenger sitting 55m from the rear of a train starts to read a newspaper article at noon and stops 42s later. (train is traveling at 21m/s) What is the spatial seperation of these events in the frame of referance of the (a) train (b) earth ?

    I'm a bit confused as to what to do. Any help would be appreciated.

    (a) 0 m

    (b) (21)(42) = 882 m
