## 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.
