Limits again

[edahcs]

For this problem, I am really unsure how you would go about solving it. In order to find the limit for L, would you plug in C for L and then solve the equation?

I don't know a lot about physics but I'm assuming the speed of light is infinite and therefore they're asking you to evaluate it as it approaches infinity? I could be wrong but I thought I'd try and help regardless.

Of course, the speed of light is a finite number.

As v --> c, 1 - v^2/c^2 ---> 1 - 1 = 0

So the length approaches 0.
