A star is 5.00 ly from the Earth. At what speed must a spacecraft travel on its journey to the star such that the Earth–star distance measured in the frame of the spacecraft is 2.00 ly?


Expert Answer

Step 1


Distance between earth and star (L) = 5.0 light year.

Earth star distance measured if the space craft move with velocity (v) is (L’) = 2.0 light year.

Step 2

The relation between distance a...
