Lesson: Time Dilation
In this lesson, we will learn how to apply Lorentz transformation to time measurements made by observers that have relative velocities to each other.

An observer standing by the railroad tracks sees two bolts of lightning strike the ends of a -m-long train simultaneously, at the instant the middle of the train passes him at a speed of 50 m/s. Find the time between the lightning strikes as measured by a passenger seated in the middle of the train.
-mesons have a proper lifetime of s. What lifetime do -mesons have as measured by an observer moving relative to them at m/s?
The lifetime of a neutral -meson is measured by an observer to be s. The proper lifetime of the -meson is s. What is the velocity of the -meson relative to the observer?
