In 2030, the Australian Space Agency launches a spaceship to our nearest neighbour Alpha Centauri (4 lightyears away). How long will the journey take according to a clock on the spaceship if it travels at v=0.999c-299482km/s (where 'c' is the speed of light equal to 299782km/s). About 6 years. Just over 2 months. About 2 years. About 4 years.
The Millennium Falcon is approximately 35.2 m long. There are conflicting reports, but the Falcon made the Kessel Run in approximately 12.27 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 0.96c during the 12.27 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. X 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? Which person would measure the proper length of the Millennium Falcon?
If astronauts could travel at v = 0.938c, we on Earth would say it takes (4.20/0.938) = 4.48 years to reach Alpha Centauri, 4.20 light-years away. The astronauts disagree. (a) How much time passes on the astronauts' clocks? years(b) What is the distance to Alpha Centauri as measured by the astronauts? light-years
If astronauts could travel at v = 0.932c, we on Earth would say it takes (4.20/0.932) = 4.51 years to reach Alpha Centauri, 4.20 light-years away. The astronauts disagree. (a) How much time passes on the astronauts' clocks? years (b) What is the distance to Alpha Centauri as measured by the astronauts? light-years
The Millennium Falcon is approximately 35.2 m long. There are conflicting reports, but the Fàlcon made the Kessel Run in approximately 12.95 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.tet's imagine that the Millennium Falcon travels at 0.95c during the 12.95 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
If astronauts could travel at v = 0.902c, we on Earth would say it takes (4.20/0.902) = 4.66 years to reach Alpha Centauri, 4.20 light-years away. The astronauts disagree. (a) How much time passes on the astronauts' clocks? In years (b) What is the distance to Alpha Centauri as measured by the astronauts? In light years
If astronauts could travel at v = 0.920c, we on Earth would say it takes (4.20/0.920) = 4.57 years to reach Alpha Centauri, 4.20 light-years away. The astronauts disagree.

The special theory of relativity has what effect on measurements done today? (a) None whatsoever, because any correction would be negligible. (b) We need to consider the effects of relativity when objects move close to the speed of light. (c) We should always make a correction for relativity because Newton’s laws are basically wrong. (d) It doesn’t matter, because we can’t make measurements where relativity would matter.
The star Epsilon Eridani is 10.4 light-years from Earth. Imagine a spaceship that travels from Earth to Epsilon Eridani 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 (10.4ly/0.921c)= 11.2 years. (a) How much time (in years) would it take the ship to travel from the Earth to the star as measured by a passenger aboard the ship? years (b) What is the distance to the star (in light years) as measured by a passenger aboard the ship?
If astronauts could travel at v = 0.950c, we on Earth would say it takes (4.20/0.950) = 4.42 years to reach Alpha Centauri, 4.20 light - years away. The astronauts disagree. (a) How much time passes on the astronauts’ clocks? (b) What is the distance to Alpha Centauri as measured by the astronauts?
Provide the correct answer in second. Previously got so many wrong answers. A muon has an average life time t_0 = 2.2μs from Earth's frame of referance. Needed distance for them to be found on earth surface is 6Km . 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 ?
The star Proxima Centauri is 4.24 light-years from Earth. Imagine a spaceship that travels from Earth to Proxima Centauri at a constant speed of 0.925c. On Earth, we would measure the time it takes for the ship to reach the star to be (4.24ly/0/925c)=4.58 years How much time (in years) would it take the ship to travel from the Earth to the star as measured by an astronaut aboard the ship? ______ years What is the distance to the star (in light years) as measured by an astronaut aboard the ship? _______ ly
