Homework Help: Density of an asteroid from revolution period

  1. Mar 12, 2008 #1
    1. The problem statement, all variables and given/known data

    The rotation period of a small asteroid is 10.21 revolutions per day. What is the minimum density for this object?

    2. Relevant equations 3. The attempt at a solution

    I should be able to use angular momentum right? I'm trying to do this by approximating the asteroid as a sphere and using the formula T = 2*pi*I /L and plan on finding the density from I, but I am stuck. Are there any relevant formulas you could point me to? Or any other hints you could give?
