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 toA, and that the length of B is 36.0 m. (a) What are the lengths of the two ships as measuredby a passenger on ship B? Spaceship A then travels to a star 95.0 light-years away at aspeed of 2.20×108 m/s. A light year is the distance light travels in one year. How long doesit take to get there (b) as measured on Earth and (c) as measured on the spaceship?

100-m 0.920 c 36.0 m 95.0 2.20×108 m/s

Your answer is partially correct. Twins who are 19.0 years of age leave the earth and travel to a distant planet 12.0 light years away. Assume that the planet and earth are at rest with respect to each other. The twins depart at the same time on different spaceships.
