1. The problem statement, all variables and given/known data An 8.0-cm radius disk with a rotational inertia of 0.12 kg m2 is free to rotate on a horizontal axis. A string is fastened to the surface of the disk and a 10-kg mass hangs from the other end. The mass is raised by using a crank to apply a 9.0-N m torque to the disk. The acceleration of the mass is: 2. Relevant equations torque = I(ang. accel) 3. The attempt at a solution I have no clue. I tried solving for the angular acceleration, but I don't know how to connect the acceleration of the mass to the acceleration of the disk.
