If the wheel has a moment of inertia is being stretched to the rotation axis easily without friction mass m planted with string wrapped around the shaft of radius r is the angular acceleration of the wheel, how much.
If the wheels are the moment of inertia is being stretched to the rotation axis conveniently without friction, mass m planting rope wound around the shaft with radial r will be accelerated angular wheel much.
