Teacher Joy and Helen are scheduled to have a class at 1:00 pm until 2:30 pm in the afternoon. Both came to class on time however, according to the guard on duty, Teacher Joy finished the class at 2:25 pm while Teacher Helen finished at 2:35 pm. However, both teachers claimed that they both finished the class on time. Explain how the special theory of relativity is involved in this situation.

The star 61 Cygni A is 11.4 light-years from Earth. Imagine a spaceship that travels from Earth to 61 Cygni A at a constant speed of 0.921c. On Earth, we would measure the time it takes for the ship to reach the star to be 11.4 ly 0.921c = 12.4 years. (a) How much time (in years) would it take the ship to travel from the Earth to the star as measured by a traveler aboard the ship? years (b) What is the distance to the star (in light years) as measured by a traveler aboard the ship? ly

A ship is heading off to Bernard's star at 0.700c. As it passes a space station (at rest with respect to the Earth) a few days out from Earth, the ship fires a "photon torpedo" in the forward direction and another in the reverse direction. the torpedoes have a speed relative to the ship of 0.700c. On a space-time diagram, determine the direction and speed of each torpedo as seen by the station. Check your answers using the relativistic addition of velocities formula.
