###### Question details

Problem 4 (25 Points) A spaceship passes the earth at t=t’=0 with relative velocity v. At time t1 on earth clocks, a super space ship leaves the earth with relative velocity V>v to catch up with the first one. This will happen at earth time t2, where vt2 = V(t2-t1) or t2=V t1/(V-v).

(a) What does the clock on the slow spaceship read when the earth clock reads t1 ?

(b) If viewed from the slow spaceship, how far from the slow spaceship is the earth at time t1 ?

(c) What does the clock on the slow spaceship register when the ship is overtaken ?

(d) In the frame of reference of the slow spaceship, how much time has elapsed since the pursuit started ? (e) In the same reference frame, how large a distance was covered in the pursuit ?
