Homework Help: Relativistic Beaming (shooting a laser at 90 degrees from your line of motion)

  1. Feb 2, 2012 #1
    1. The problem statement, all variables and given/known data
    A ship is traveling at a speed of .8c. When the ship is 90 degrees from the target, it shoots a laser downwards. What angle must it shoot the laser to hit the target?

    2. Relevant equations
    [itex]\mu_{x}=0[/itex]
    [itex]\mu_{y}=-c[/itex]
    [itex]\mu_{x}'=[/itex][itex]\frac{mu_{x}-v}{1-\frac{v*mu_{x}}{c^{2}}}=-v[/itex]
    [itex]\mu_{y}'=[/itex][itex]\frac{mu_{y}}{1-\frac{v*mu_{x}}{c^{2}}}=-.6c[/itex]

    3. The attempt at a solution
    I have tried everything I can think of, but nothing seems to work..
    I have gotten to this point and I'm fairly sure this far is at least right. Does anyone know where to proceed from here?

    Thanks in advance,
