## Homework Statement

The position vector of a 1.0-kg particle is given by r = 4 i + 3 j + 3 k and its velocity by v = 5 i - 2 k. Find the magnitude of the particle's angular momentum in kg.m2/s.

## Homework Equations

L=Iω

or

L=mvr

## The Attempt at a Solution

This question is a real curve ball because I don't exactly know how to make sense of using this scalar system. I know that the object is moving in a linear path and that I am trying to find the angular momentum in relation to the origin. This means the angular momentum must be the same along the entire path. Thus the angular momentum would be mass*velocity*distance from the path of the particle to the parallel line extending from the origin. Since this problem is in the scalar form I don't really know what to do. I don't want an infraction so if you have any thoughts to help me move along that would be great. I have searched the internet to sources but nothing clarifies it well for me. I used hyperphysics.com which is usually great. Post any links that might help. Thanks.
