Module 24: Lorentz Transformation: Examples - Problem 7
Continuing on from the previous problem, now imagine that Bart has two friends, Itchy and Scratchy, equidistant from him at $x^\prime=-L^\prime /2$ and $x^\prime=L^\prime /2$, respectively, who set off their own firecrackers when the light from Bart’s firecracker reaches them. As this is happening, Lisa races by Bart on her own skateboard at speed $w$ in the positive $x^\prime$-direction.
