You are the captain of spaceship A that leaves Earth at t=0traveling at 0.6c. An identical spaceship B, whose captain is yourtwin brother, leaves Earth a time t1 later, according to Earth'stime, traveling in the same direction as you and catches up withyou in 25 years of Earth's time. As your twin brother passes you hetells you that his ship is 50m long but yours is only 40m long.

a) what is the relative speed of one spaceship as seen by the other?

b) What is t1?

c) Which of the captains feels older at this time andby how much?
