Question

A rotating platform is on a table and an object is on the platform. The platform has a diameter of 30.0cm and it has a string wrapped around it. The string is threaded over a pulley ( which is right next to the platform and attached to the edge of the table ) . The pulley also has a mass hanging. The mass is then released (from rest) and its acceleration a is determined when calculated.
Moment of inertia from pulley is ignored
Calculate the total moment of inertia of the platform and the object
