Abucket of mass m is hanging from the free end of a rope whose other end is wrapped around a drum (radius r, mass m) that can rotate with negligible friction about a stationary horizontal axis. the drum is not a uniform cylinder and has unknown moment of inertia. when you release the bucket from rest, you find that it has a downward acceleration of magnitude (a). what is the tension in the cable between the drum and the bucket? (b) what is the moment of inertia of the drum about its rotation axis?
c) in the primitive yo-yo apparatus (figure 1), you replace the solid cylinder with a hollow cylinder of mass m, outer radius r, and inner radius r/2. find the magnitude of the downward acceleration of the hollow cylinder. what is the tension?
