Homework Help: 2 Spaceships travelling towards a blackhole.

  1. Apr 14, 2010 #1
    1. The problem statement, all variables and given/known data
    From our perspective a spaceship is traveling towards a black hole 9 light minutes away at 0.995C, another spaceship is traveling towards the black hole, traveling at a -0.03c from the point of view of the first spaceship. is it possible for the first spaceship to stop the second going into the black hole?


    2. Relevant equations
    t'=γ(t-(v/(c^2)))
    x'=γ(x-Vt)
    I think...

    3. The attempt at a solution
    As I don't know the position of the second spaceship, i spent an hour trying to figure various speeds/distances from both points of view, but ended up not getting anywhere.
