Homework Statement



A diver is spinning, I know the moment of inertia and the angular velocity. I've been asked to calculate angular momentum. Just H=Iw (yes?) Just when I show the answer is it kg.m or radians?

Homework Equations



H=Iw

The Attempt at a Solution



I=18kgm2
w = 7.9 rad/s

H= (18kgm2)(7.9rad/s)
H= (324kg.m)(7.9rad/s)
H=142.20 kg.m ?

Couldn't get your question...
Angular momentum is always calculated about a point. If that point is the center of mass of the body, the the value of ang momentum is Iw!
