Two spaceships pass each other traveling in opposite directions. A passenger on ship A, which she knows to be 100-m long, notes ship B is moving with a speed of 0.920 c relative to A, and that the length of B is 36.0 m. (a) What are the lengths of the two ships as measured by a passenger on ship B? Spaceship A then travels to a star 95.0 light-years away at a speed of 2.20×108 m/s. A light year is the distance light travels in one year. How long does it take to get there (b) as measured on Earth and (c) as measured on the spaceship?
