Need help with meter stick problem

  1. Apr 20, 2005 #1
    I know the formula to use for this problem, but cannot seem to make
    it come out with a reasonable answer. Can anyone help?

    If a meter stick travels at the speed of light relative to an observer,
    how long does the meter stick appear to the observer?

    (I cannot seem to make the radical sign or the exponents look right,
    but I will do my best!)
    Formula: L=Lo (RADICAL SIGN) 1 -v(exponent 2) / c(exponent 2)

    Thanks

    Trick question. You should not *get* a reasonable answer. Why?

    The root of your problem is that:

    A meter stick can't travel at the speed of light relative to an observer.
