college level physics problem


A ball with uniform mass density rolls without slipping on a turntable.

Show that the ball moves in a circle (as viewed from the inertial lab 
frame), with a frequency equal to 2/7 times the frequency of the turntable.



[hint: assume angular velocity of turntable, then of the ball, and 
realize the friction force from  the turntable is responcable for 
changing both the balls linear momentum and its angular momentum.  I 
classify this problem as hard. ]
