Two spheres are each rotating at an angular speed of 23.7 rad/s about axes that pass through their centers. Each has a radius of 0.360 m and a mass of 1.68 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 = 0.400 N · m) begins to act on each sphere and slows the motion down. How long does it take (a) the...
