- Activity 2.2. Shrinking Ship Danny is driving a spaceship with a length of 60 meters at the speed of .32c and is observed by Susan in the direction relative to her. Based on this situation, identify the perceived length of the space shuttle using the principle of length contraction. In addition, describe what happened to the length of the space shuttle. Moreover, describe what will happen to an object as it reaches the speed of light.arrow_forwardSolve this relativity problem using Lorentz transformations. Step by Step. An observer on earth watches a 25 meter long spacecraft pass by at relativistic speed for two hours. An astronaut traveling inside the ship measures his characteristic time as half an hour.Before starting the space flight he was informed that his ship was 100 meters long.what was the speed at which the ship was moving?arrow_forwardProvide the correct answer in second.

- 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.arrow_forwardThe 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?

- Albert Abraham Michelson became the first American to win the Nobel Prize in Physics in 1907 for his work on improved measurements of the speed of light. If his descendants wanted to leave Earth and travel to a star 300 light-years from Earth to receive a radio transmission sent in 1907 announcing his award, how could they do so? a)Travel in a ship in which the proper time is less than 300 years. b)Travel in a ship in which the proper time is more than 300 years. c)They could not - it would require travelling faster than light, which is impossible. d)Launch a rocket which leaves Earth at 99.99% of the speed of light, then launch a second stage from the rocket, which moves away from the first stage at 99.99% of the speed of light.arrow_forwardYou travel to a distant planet in a spaceship. The speed of your spaceship is 0.917c, corresponding to a gamma factor of y=2.5. When you reach the planet you immediately turn around and return to Earth, also at speed 0.917c. When you arrive back at Earth you are 5 years older than when you left.

You are a space traveller, moving at 0.60c with respect to Earth, on your way to a star that is stationary relative to Earth. You measure the length of your trajectory to be 8.0 light-years (y). Your friend makes the same journey at 0.80c with respect to Earth. What does your friend measure the length of the trajectory to be? 7.
