Homework Statement



I am just confused about Angular momentum.

Homework Equations




KE(rotational)= 1/2Iw^2
Angular momentum= Iw

The Attempt at a Solution



Why can I do the change in KE rotational to calculate the her final angular velocity in 3 revs?
very confused!! :( both equations relate to moment of inertia and angular velocity.

Only angular momentum is conserved here. That's all you need.
