Message: <blockquote data-quote="georgy g" data-source="post: 120909">inertia of 520 kgÂ·m2 and a radius o A 60 kg woman stands at the rim of a horizontal turntable with a moment of inertia of 520 kgÂ·m2 and a radius of 1.5 m. The system is initially at rest, and the turntable is free to rotate about a frictionless vertical axle through its center. The woman then starts walking clockwise (when viewed from above) around the rim at a constant speed of 1.5 m/s relative to the Earth.(a) In what direction and with what angular speed does the turntable rotate?_____Rad/sclockwise or counterclockwise?(b) How much work does the woman do to set the system in motion?_______</blockquote>
