Chapter 09, Problem 83 Chalkboard Video Two spheres are each rotating at an angular speed of 21.9 rad/s about axes that pass through their centers. Each has a radius of 0.430 m and a mass of 1.66 kg. However, as the figure shows, one is solid and the other is a thin-walled spherical shell. Suddenly, a net external torque due to friction (magnitude-0.1 20 N·m) begins to act on each sphere and slows the motion down. How long does it...
