## Homework Statement

A large turntable of radius 6 m and moment of inertia I = 500 kg m^2

about its center is rotating with an angular velocity of 1 radian/s. A girl of mass 30 kg standing at the exact center moves slowly outward to the edge of the turntable.

a) What is the angular velocity of the turntable when she reaches the edge?

b) Now that she is at the edge what is the minimum coefficient of static friction between the girl and the turntable such that she remains fixed at the edge without slipping?

## Homework Equations

L = Iω, mRω^2= u mg, K =1/2 Iω^2

Not sure what else?

## The Attempt at a Solution

I played around with the moment of inertia equation for a disc, but didn't get very far. I'm not sure how I can relate velocity to everything (I missed all of these classes since I was really sick).
