Chapter 11, Problem 57PCE

Predict/Calculate A turntable with a moment of inertia of 5.4 × 10⁻³ kg · m² rotates freely with an angular speed of $33\frac{1}{3}$ rpm. Riding on the rim of the turntable 15 cm from the center, is a cute. 32-g mouse (a) If the mouse walks to the center of the turntable, will the turntable rotate faster slower, or at the same rate? Explain (b) Calculate the angular speed of the turntable when the mouse reaches the center.
