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?

Homework Statement gammav is a reasonable measure of the size of relativistic effects. Roughly speaking, at what speed would observations deviate from classical expectations by 1%? Homework Equations gammav = 1/ [sqrt91.v2) / c2] The Attempt at a Solution I've honestly puzzled...

Okay. So does that mean that I should use the formula t = gammav x t0 ? Then I could plug in 100 x 10-6 for t0 since this is how long it took in anna's frame of reference? This gives me 1.25 x 10-5 as my t. and then can I use this t instead to find length? But I still get a very similar...

Homework Statement Anna is on a railroad flatcar moving at 0.6c relative to Bob. Her arm is outstretched in the dirction the flatcar moves, and in her hand is a flashbulb. According to her wristwatch, the bulb goes off at 100 ns. This even according to Bob differs by 27 ns. a) is it earlier...
