Astar is moving away from the earth at a speed of 0.60 c as measured in an inertial system s, at rest with respect to the earth. at time t-0, when the star is 109 ly away as measured in s, the following two events occur simultaneously as observed in s: 1-a bomb explodes nearby the earth 2- a bomb explodes on the moving star. give the space and time coordinates for events 1 and 2 as observed in s', which is at rest with respect to the star, according to a) galilean transformations and b) lorentz transformations.
