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:
