Question 1: You wish to travel to a planet located 10 light years (ly) away. a)...
The distance to Planet (X) is 4.70 ly. How long does it take a spaceship to reach the planet, according to the pilot of the spaceship, if the speed of the ship is 0.90c?
Tau Ceti is a star that is located 11.753 ly away. There is a planet orbiting this star with an orbital radius of 0.538 AU (AU stands for astronimcal unit - the average distance between Earth & the Sun). Fill in the table below by determining the minimum diameter the objective of a telescope would need to be in order to resolve the planet from the star at the stated wavelengths. 1 ly = 9.461 × 1015 m & 1...
A space probe is to travel from Earth to a refueling station 5.05 ly away. At what speed must the probe travel in order for the Earth–station distance to be 2.45 ly, when measured in the reference frame of the probe? Express your answer as a multiple of c, the speed of light in a perfect vacuum. c
In an Earth reference frame, a star is 76 light-years away. How fast would you have to travel so that to you the distance would be only 39 light-years?
How fast should you fly to a planet 50 light years away if you want to get to your destination in one year of your own time?
The nearest star to Earth is Proxima Centauri, 4.3 light-years away. Part A At what constant velocity must a spacecraft travel from Earth if it is to reach the star in 4.9 years, as measured by travelers on the spacecraft? b: How long does the trip take according to Earth observers? in years
You travel in ship 2) You travel in your ship White Star One at a constant speed of v 0.96*c to the nearby star Proxima Centauri, located 4.2 light years away from Earth. a. From your point of view in the ship, how far is the star from the Earth? b. If your mass is 68 kg, what is your kinetic energy while moving with the ship? c. How long does the journey take, according to clocks on your ship?...
Suppose you decide to travel to a star 69 light-years away at a speed that tells you the distance is only 28 light-years. Part A How many years would it take you to make the trip? Express your answer using two significant figures.
A 22 year-old biologist makes a trip to study life forms in a distant planet 18 light-years away. The round trip including a stay of 1 year in the distant planet takes 40 years according to the clock on earth. The biologist's son is 2.5 year-old when she left. Assume that the planet is not moving with respect to earth. 1.How fast is the spaceship traveling? Give your answer in terms of the speed of light. You do not need...
The nearest star from our system is 4.3 ly away. How fast must a starship travel if the passengers are to age 2.0 years for the trip.
