Consider a hoolahoop of radius R and it is spinning about its symmetry axis at a constant angular velocity. Now, I double its mass and halve its angular velocity. What is the new angular momentum in terms of the initial angular momentum?

PHYSICS HELP! 
Damon,
L = I w = m R^2 w
L2 = 2 m R^2 w/2
which is the same
