Homework Help: Bouyancy - throwing rock overboard

  1. Dec 3, 2006 #1
    k in my advanced physics class 32S we are doing a project on buoyancy, one of the questions we have to answer is if you go out in a pool in a boat with a rock in it, then you throw the rock over board will the water level go up/down/stay the same. I am pretty sure that the water level will go up but do not know how to explain this, any help?

    Welcome to the Forums Crusader,

    For future reference there are Homework forums dedicated to answering such questions.

    With respect to your question, it may be useful to consider Archimedes principle...
