Homework Help: Submarine in ocean

  1. Apr 5, 2012 #1
    1. The problem statement, all variables and given/known data
    A submarine that weighs 10,000kg in air and has a volume of 12m3 floats in a harbor. How much of its volume do we need to flood in order to just begin sinking it in salt water with a density 1.02 g/cm3?

    2. Relevant equations

    3. The attempt at a solution
    Fgravity = mass of object * g = volume of object * density of object * g
