I originally used the equation Li=Lf

where Li= Iw= (1/2)(MR^2)wi which equals (.5)(210kg)(2.0^2)(1.5rad/s)

Li= 630

Lf= (If1+ If2)(wf)

=[(.5)(150)(2.0^2) + (60)(0.5^2)]wf

This gave me wf= 2.0 rad/s but that doesn't seem to make sense wouldn't the angular speed slow down as the student went closer to the center? Any hints as to where I went wrong is greatly appreciated.
