Homework Help: Relativity length contraction problem

  1. Aug 21, 2010 #1
    1. The problem statement, all variables and given/known data

    A meter stick moves with speed .8c relative to frame S. What is the length observed by a person in frame S if the stick is 60 degrees to v, as measured in S?

    2. Relevant equations
    L=observed length
    l=proper length
    y=1/sqrt(1-B^2)
    L=l/y


    3. The attempt at a solution
    Sorry, I suck at latex so heres a picture:

    You need to use the information about the angle. Hint: What does tan 60 equal?
