An unskilled DJ is chewing some very dense (to be later thought of as a point mass) Big League Chew while spinning records with his pals. The platen and record combined appear as a "solid cylinder or disk" with a diameter of 30cm and a mass of 700 grams. The DJ is working in some kids theme music (let us suppose Disney), and the spindle speed is 45 RPM.
