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?

Which person measures the proper distance of the trip?
Which person would measure the proper length of the Millennium Falcon?

A light year (LY) is the distance that light travels in one year.
1 LY = 9.46x1015 m.
Suppose we have detected a planet that orbits a star that is 104 light
years away. How many millions of years would it take us to get there if
we used a modern rocket with a maximum speed of 20.0 km/s (about
45,000 mph)? Assume 3 sig figs.
Suppose we find an Earth-like planet around one of our nearest stellar neighbors, Alpha Centauri (located only 4.4 light-years away). If we launched a "generation ship" at a constant speed of 1500.00 km/s from Earth with a group of people whose descendants will explore and colonize this planet, how many years before the generation ship reached Alpha Centauri? (Note there are 9.46 ××1012 km in a light-year and 31.6 million seconds in a year.

- A light-year is the distance that light can travel in one year. Similarly, we can define a light-second, light-day, etc. as the distance that light can travel in other time intervals. Calculate the distance represented by each of the following: (Assume that the speed of light is 3 x 10^8m/s) 5 light-minutes 6 light-days 6 light-days, but this time answer in miles (enter just the number with no units)arrow_forwardmathematician Archimedes, responding to a claim that the number of grains of sand was infinite, calculated that the number of grains of sand needed to fill the universe was on the order of 1063.

- I'm having trouble completing the problem I've attached a picture of below. I was able to find the the Earth's average speed in m/s relative to the sun by doing (2pi*(1.49x10^11))/31536000. But I am struggling to find the average velocity for the same thing over a period of one year in m/s. I was wondering how to calculate that? I've tried doing the (final velocity-initial velocity)/2 but the program doesn't accept my answer when using that approach.arrow_forwardAstronomers frequently say that “there are more stars in the universe than there are grains of sand on all the beaches on the earth”.

- The Tully-Fischer method relies on being able to relate the mass of a galaxy to its rotation velocity. Stars in the outer-most regions of the Milky Way galaxy, located at a distance of 50 kpc from the galactic centre, are observed to orbit at a speed vrot = 250 km s−1.
