Jessica stretches her arms out 0.6 m from the center of her body while holding a 2 kg mass in each hand. She then spins around on an ice rink at 1.1 m/s.

What is the combined angular momentum of the masses?

spinning is done in rad/s  !!

do you get that?

anonymous · Answer

I need to use the formula l=mvr and add all the masses together. How do I do that?

ikram002p · Answer

so this kind of spinning?

anonymous · Answer

Yes I assume so

hulahoop · Answer

i am good at spinning, can i help?

anonymous · Answer

Hahaha love the John Abraham pic!

hulahoop · Answer

don't laugh at me please.  God made me this way.

i think if you cast @ikram002p 's drawing in a 2D way, you will get the idea.

i can have a go, if you like.

anonymous · Answer

Sure I can use all the help I can get!

ikram002p · Answer

lol!

but yeah give a try :-\ as Hula said  try to determine L,m,v... (recall i don't like symbols)

anonymous · Answer

I think L = linear momentum, m = mass, and v = angular velocity if I am not mistaken.
