1. Some jets emitted by galaxies, for astronomical distances large enough, can appear to travel faster than thespeed of light c, through our line of sight. Suppose that a distant galaxy, AB15, is moving with speed v at an anglee with respect to the earth and it emits two light rays separated by a time At in its local time. show thata) The time interval on earth in which the two light rays are emitted is given byAtr = At(1– B cos 0)b) The apparent speed of AB15 measured by an observer on earth isArTVA =AttB sin e1-B cos 0%3Dc) For B = 0.75, calculate the value of 0 for which Va =c

Given data: The speed of light is denoted by c. The speed of the galaxy is v. The angle is θ. The…

1. You want to travel into the future . If your space ship can go at a speed of 2.00 x 108 m / s , how long would you have to be gone to return to an Earth five years into the future ? 2. At your speed in the previous question , by what factors would an observer on Earth see your length and mass to have changed ? How would you see the Earth's mass and length ? Why ?
The distance from earth to the center of our galaxy is about 27,000 ly (1 ly = 1 light year = 9.47 × 10¹5 m), as measured by an earth-based observer. A spaceship is to make this journey at a speed of 0.9990c. According to a clock on board the spaceship, how long will it take to make the trip? Express your answer in years. (1 yr is equal to 3.16 × 107 s.) Number i Units
v2 The formula for length contraction gives the length of an interval on a ruler moving with velocity v relative to an observer as L' = L 1 where L is the length of the same interval on a ruler at rest with respect to the observer. By what fraction is the length of a meter stick reduced if its velocity relative to you is measured to be 67 percent of the speed of light? L- L'
Setup: A futuristic trip from Earth to Alpha Centauri is taking place. The travellers 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. a) Team A travels with a constant acceleration so that their worldline can be parametrized by the proper time Tau as t(Tau) = a-1sinh(a*Tau) x(Tau) = a-1(cosh(a*Tau) - 1) for a constant 'a.' They blast off at (t, x) = (0, 0) and travel with this constant acceleration until they reach Alpha Centauri at Earth time of 10 years. What proper time does Team A measure (in years)?
2. A ladder 6.00 m long leans against a wall inside a spaceship. From the point of view of a person on the ship, the base of the ladder is 2.10 m from the wall, and the top of the ladder is 5.62 m above the floor. The spaceship moves past the Earth with a speed of 0.86c in a direction parallel to the floor of the ship. Find the angle the ladder makes with the floor, as seen by an observer on Earth. 239119 16 oci
The Millennium Falcon is approximately 35.8 m long. There are conflicting reports, but the Falcon made the Kessel Run in approximately 12.86 parsecs. This is an odd unit to measure speed with as a parsec is a unit of length equal to 3.26 light-year. The science FICTION comes in when you consider that ships in Star Wars use hyperdrive to travel faster than the speed of light, so they are able to make jumps through space. Han Solo picked difficult or dangerous points to jump between to make the trip so short. Let's imagine that the Millennium Falcon travels at 0.97c during the 12.86 parsec Kessel Run. What distance, in light-year, does an observer at the finish line measure for the trip? Don't forget to convert parsec to light-year. light-year What distance, in light-year, does Han Solo measure for the trip as he pilots the ship? light-year Which person measures the proper distance of the trip?

8.) A star is 53 Light years away, as measured by an observer on Earth. (The star is not moving relative to Earth.) You are on a rocket ship traveling from Earth to the star at a relativistic speed. To you, the distance from Earth to t he star looks: a) longer than 53 Light years, b) shorter than 53 Light years, c) exactly 53 Light years.
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…

A rocket ship traveling near the speed of light appears to a stationary observer to shorten with speed. A rocket with a length of 200 meters will appear to a stationary observer to have a length of 200 Sqrt[1-r^2]meters, where r is the ratio of the velocity of the ship to the speed of light. What is the apparent length of the rocket ship if it is traveling at a speed that is 99% off the speed of light?
