A potter is shaping a bowl on a potter's wheel rotating at constant angular velocity of 1.8 rev/s. The friction force between her hands and the clay is 1.6 N total. Part A How large is her torque on the wheel, if the diameter of the bowl is 9.0 cm? Express your answer to two significant figures and include the appropriate units.   Part B How long would it take for the potter's wheel to stop if the only torque acting on it is due to the potter's hands? The moment of inertia of the wheel and the bowl is 0.11kg⋅m2. Express your answer to two significant figures and include the appropriate units.
