- 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.What is the number of miles in a light-year, using (see picture) mi/s as the speed of light? I know the number of seconds in a year and 365 days will help but confused on how to put it in the equation.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.
- If a space ship traveling at 1/5 the speed of light travels to a star system 6 light years away How many years would it take the craft to get there and back?A star is 80 light years from Earth. How fast does a spacecraft have to be for the journey to last the 70 years of an astronaut's life? The answer is 0,7526c. Show a complete approach on how to get to the answer by using the necessary equations.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)
- How many miles in a light year?If there are 3x10^7 seconds in one year, a distance of one light year is equal to: 9 x 10^15 m 9 x 10^13 m 9 x 10^11 m O 9 x 10^9 mSuppose 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.
- if you walk at 1km/hr down the aisle of a train that moves at 60km/hr, what is your speed relative to the ground?The moon is 1.3 light-seconds away. Imagine you are standing at the Canadian Space Agency headquarters in St. Hubert, Quebec and you bounce a 755 MHz radio signal off the moon (the moon acts like a mirror, reflecting the signal, such that it comes back to you). How long will it take for that radio signal to get back to you on earth? Answer in seconds with one decimal place.As measured on Earth the star Fomalhaut is 25.1 light years away. As measured by the crew of a spaceship that flies to Fomalhaut, the distance is 8.6 light years. In years, calculate the duration of the trip as measured by the crew of the ship.(Give your answer in years but don't include the units.)
