A pirate starship in the distant future is being chased by the space police. The pirates are traveling at 1153 km/h while the police are traveling at 1289 km/h. The pirate ship needs 25 minutes to turn on its faster-than-light drive so it can jump into hyperspace to escape.
How long, in minutes, will it take the space police to catch up to the pirates if they are 50 km away from one another?
It is year 2120 and we have figure out a propulsion system that allows
spaceships travel at velocities as high as v = 0.87c. A first expedition to
Alpha Centauri (the nearest planetary system) is being planned. Alpha
Centauri is 4.3 ly away.
Answer the following 5 questions below asking you about the details of
this expedition.
Question 10

- Travel to the stars requires hundreds or thousands light. Some people have suggested that we can get around this difficulty by accelerating the rocket (and its astronauts) to very high speeds so that they will age less due to time dilation. The fly in this ointment is that it takes a great deal of energy to do this. Suppose you want to go to the immense red giant Betelgeuse, which is about 500 light-years avway. You plan to travel at constant speed in a 1000 kg rocket ship (a little over a ton), which, in reality, is far too small for this years, even at the speed of Part H If the rocket ship's speed is 0.990c, calculate energy needed as a percent of U.S. yearly use (which is 1.0 x 1020 J).

Answer the following 5 questions below asking you about the details of this expedition.arrow_forwardParticles accelerators such as the Large Hadron Collider (LHC) can accelerate particles up to tremendous energies. Suppose the LHC accelerates alpha particles (a.k.a. helium nuclei with a charge of +2e and a mass of 6.645 x 10-27 kg) with a kinetic energy of 7.5 TeV*, what would the speed of one particle be if relativistic effects** are ignored? Give your answer in units of Gm/s. *T as in Tera, for 1012. "eV" stands for "electron volt," which is a non-Sl unit of energy equal to what one electron would gain after travelling through 1V. 1eV = 1.602 x 10-19 J. **Special relativity is necessary to correctly account for the limiting speed of light, which is about 3 x 10° m/s. Note that in ignoring this effect and applying Newtonian mechanics (what you learned in Phys1210 or equivalent), you'll be getting a speed way above 0.3 Gm/s. That's just how insanely energetic the LHC is.arrow_forward

What is the average life time of muon from it's own frame of referance if they are travelling with an speed of 2.978×108 m/s ?arrow_forwardQuasars are faint, distant sources of radio waves. (Quasar is short for "quasi-stellar source." They are so named because, like a star, they appear to the astronomer to be pointlike.) From the shift in the frequency of their emitted light toward the red, called the "redshift," we know that quasars are moving very fast. Astronomers observe that the more distant an object is from the earth, the faster it moves. In this way they determine that quasars are billions of light years from earth. To be visible at this great distance, quasars must have enormous luminosity. Typically a quasar radiates energy at a rate on the order of 1040 W, roughly 1014 times greater than the sun or 40 times greater than the most luminous galaxy. At what rate is rest mass being consumed to produce this much radiation? Quasar 3C-273arrow_forward
