With axle and spokes of negligible mass and a thin rim, acertain bicycle wheel has a radius of 0.350 m and weighs 33.0 N; itcan turn on its axle with negligible friction. A man holds thewheel above his head with the axle vertical while he stands on aturntable that is free to rotate without friction; the wheelrotates clockwise, as seen from above, with an angular speed of66.0 rad/s, and the turntable is initially at rest. The rotationalinertia of wheel + man + turntable about the common axis ofrotation is 2.00 kg·m2. The man's free hand suddenly stops therotation of the wheel (relative to the turntable). (a) Determinethe resulting angular speed of the system. (b) Is the direction ofthe rotation clockwise or counterclockwise?
