Physics

Problem

A scientist stands at a train station platform and observes a high-speed train moving away from her at velocity v=0.6cv = 0.6c. At the exact moment the train passes her position, she emits a light pulse toward the back of the train using a laser pointer. The train has a proper length of L0=300  mL_0 = 300\;\text{m}. From the scientist's reference frame, how long does it take for the light pulse to reach the back of the train?
