A potter's wheel,with rotational inertia 46 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? A)8.0 kg B)5.4 kg C)7.0 kg D)8.8 kg

Question

Quizplus · Accepted Answer

Using the conservation of angular momentum, the initial angular momentum (I_initial * ω_initial) equals the final angular momentum ((I_initial + m * r^2) * ω_final). Solving for m gives 8.0 kg.
