bucket 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 are (a) the tension in the cable between the drum and the bucket and (b) the moment of inertia of the drum about its rotation axis?

Question
bucket 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 are (a) the tension in the cable
between the drum and the bucket and (b) the moment of inertia of the
drum about its rotation axis?
