In a frame S, two events are observed: event 1: a pion is created at rest at the origin and event 2: the pion disintegrates after time τ . Another observer in a frame S′ is moving in the positive direction along the positive xaxis with a constant speed v and observes the same two events in his frame. The origins of the two frames coincide at t = t′ = 0. (a) Find the positions and timings of these two events in the frame S′ (a) according to the Galilean transformation, and (b) according to the Lorentz transformation.
