A potter's wheel, with rotational inertia 12 kg-m², is spinning freely at 40 rpm. The potter drops a lump of clay onto the wheel, where it sticks a distance 1.2 m from the rotational axis. If the subsequent angular speed of the wheel and clay is 32 rpm what is the mass of the clay? O 1.4 kg O 2.3 kg O 1.8 kg O 2.1 kg
