1. The problem statement, all variables and given/known data Two relativistic rockets move toward each other. as seen by an observer on earth rocket A of proper length 500m travels at a speed of .8c and rocket b of proper length travels at speed .6c. What is the speed of the rockets relative to each other? the earthbound observer sets her clock to t=0 when the noses of the rockets pass each other. what will the observers clock read when the tails pass eachother? 2. Relevant equations (u-u')/(1-uu'/c^2)=v x'=[tex]\gamma[/tex](x-vt) t=[tex]\gamma[/tex]to 3. The attempt at a solution I got the first part which was .95c. the second part I started by calculating the length contraction x'a sqrt(1-(.8c/c)^2)=xa=300m x'b(1-(.6c/c)^2)=xb=800m but then I got totally lost.
