Special relativity concept question

  1. Sep 28, 2011 #1
    1. The problem statement, all variables and given/known data

    gammav is a reasonable measure of the size of relativistic effects. Roughly speaking, at what speed would observations deviate from classical expectations by 1%?

    2. Relevant equations

    gammav = 1/ [sqrt91.v2) / c2]

    3. The attempt at a solution

    I've honestly puzzled over this question for hours, and have gotten nowhere. Any hints would be greatly appreciated. I have no idea where to even start. I know that I need gammav to be equal to 1.01 for it to be 1% different from classical physics. . .
    However I'm not sure where to go from here.

    Why not set up an equation expressing this and then solve for v?

    so 1.01 = 1/ [sqrt(1 - v2) / c2]
    But now I have 2 unknowns..c and v right? So how do I isolate just v?

    c is not an unknown, it's the speed of light! Your answer for v will be in terms of c. Just solve for v like you normally would.
