Homework Help: How to Calculate Angular Momentum ?

  1. Sep 27, 2012 #1
    1. The problem statement, all variables and given/known data

    You and your best friend are at sea on your ship. Your
    ship is designed to withstand seas during 120 knot winds. You measure the winds
    outside your ship at 30 knots. From satellite images and Global Positioning System
    (GPS) data, you pinpoint your position at 60 nautical miles from the centre of a
    hurricane. The satellite image shows that the eye of the hurricane hasn't changed
    position in hours and that the diameter of the eye is 20 nautical miles.

    2. Relevant equations

    AM= M X V X R

    3. The attempt at a solution

    30*60 = v2 * 20

    I'm kinda lost on what to do beyond this.

    You have not stated what you are supposed to find.

    I am suppose to find angular momentum from the above data.

    Angular momentum of what with respect to what?

    Angular momtemum of the hurricane and see if my ship could withstand angular momentum of the hurricane.

    I am not completely sure you could apply conservation of angular momentum here, but assuming you can, the formula you have is correct. But the computation is not.
