Homework Help Overview

The discussion revolves around calculating angular momentum in the context of a ship's position relative to a hurricane. The original poster describes a scenario involving wind speeds and distances from the hurricane's eye, aiming to determine the angular momentum associated with the hurricane.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the definition of angular momentum in relation to the hurricane and the ship's position. Questions arise regarding the specifics of what is being measured and the applicability of conservation of angular momentum in this scenario.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the problem's requirements and the parameters involved in calculating angular momentum. Some guidance has been offered regarding the formula, but there is no consensus on the approach or the validity of assumptions made.

Contextual Notes

There is uncertainty regarding the specific quantities to be calculated and the assumptions about applying conservation of angular momentum in this context. The original poster's initial computation has also been questioned for accuracy.

Homework Statement



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.

Homework Equations



AM= M X V X R

The Attempt at a Solution




30*60 = v2 * 20
v2=60

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.
