Assume the Galilean transformation equations are true. Suppose that construction crews have set up a pair of blinking lights 60 m apart to mark a construction zone along a road. A car moves along the road with a speed of 30m/s toward the lights. Let us take the road to be the Home Frame and the car to be the Other Frame. In the Home Frame, the light farther from the car (light 2) blinks 0.66 s before the other light (light 1) blinks as the car approaches. (a) What is the time interval (t'2 - t'1) between the blink events in the car's frame? (Hint: Think about the sign - should it be negative?). (b) What is the x displacement x'2 - x'1 between the events in the car frame?

A spacecraft is moving at speed 0.61c relative to two star systems—star system A and star system B— that are always the same distance apart with respect to each other. Observers aboard the spacecraft measure the time taken to travel from start system A to star system B as 23.22 years. What is the distance between the two star systems, in light-years, as measured by an observer that is bound to star system B.
While flying past a space station at 0.500c, and at precisely 6.00 seconds before arriving at the station (as measured on the ship's clocks), a starship fires a hyperprojectile forward at 0.700c as measured in the ship's frame of reference. How fast is the projectile moving as seen by the space station's crew?
Twins who are 19.0 years of age leave the earth and travel to a distant planet 12.0 light-years away. Assume that the planet and earth are at rest with respect to each other. The twins depart at the same time on different spaceships. One twin travels at a speed of 0.905c, and the other twin travels at 0.407c. (a) According to the theory of special relativity, what is the difference between their ages when they meet again at the earliest possible time? A₂-A₁ = (b) Which twin is older?
The inertial reference frames, S and S', both share the same origin at t = t'= 0. The 5' trame is moving at a speed 0.700c in the positive direction, as seen by frame S. An event happens at (1', x', y', z') = (300s, 2.50×10m,1.50×10"m, 2.90x10"m), as observed in the S' frame. What are the spacetime coordinates in the S frame?
Setup: A futuristic race from Earth to Alpha Centauri is taking place. But the winner of the race isn't who gets there first, it's who measures the smallest proper time along the way. The competitors start on Earth, from position (t, x) = (0, 0). They must travel from Earth (considered stationary) to Alpha Centauri, a distance of L = 4.37 light years away, such that they arrive at Alpha Centauri at Earth time of T = 10 years. Upon arrival, they compare their personal times (the proper time they measure along their whole trip) and the team with the smallest proper time wins. Question: a) Team A's spaceship immediately blasts off at (t, x) = (0, 0) and travels at a constant speed until they reach Alpha Centauri at Earth time of 10 years. Team B, on the other hand, have a much faster ship— they can travel so fast, you may consider their maximum speed to be the speed of light. Team B stays stationary on Earth for as long as they can; then, they blast off and travel at constant maximum…
Two friends, Sungyoung and Azhar are initially 10 years old. While Azhar remains on Earth, Sungyoung rides on a spaceship which travels away from Earth at a speed of 1c for 5years (as measured by Azhar), then immediately turns around and comes back at 1c. When Sungyoung returns, Azhar is 2*5 years older than when Sungyoung left. How old is Sungyoung upon his return?

Michale is decided to buy a ticket to go to space. After meticulously planning his journey, he travels in his vessel at speed 7/10c from Earth to the nearby planet, Alfa-0 , 20 light-years away (as measured in the common rest frame of Earth and Alfa-0). He spends a year (as measured in Earth- Alfa-0 frame) on this foreign planet sharing stories of human history to aliens. Finally, he is ready to head home. His hosts, charmed by his friendliness and the stories of his wonderful home, give him their best space ship for the return voyage. In this new ship, he travels at speed 95/100 c. Let W be Michael's departure from Earth (which we can set as the origin of the reference frame), X his arrival to the Alfa-0, Y his departure from the Alfa-0, and Z his arrival back to Earth. a. Draw the spacetime diagram from the rest frame of the Earth - Alfa-0 system, indicating Michale's worldline, and the events, W, X, Y, Z. (A rough sketch will suffice - do not worry about the angles. b. Find the…
