Final answer:
The correct answer is D. Shape the pot so that it has a wider rim because the angular velocity of an object decreases when its moment of inertia increases.
Step-by-step explanation:
The correct answer is D. Shape the pot so that it has a wider rim.
When the pot is shaped with a wider rim, it increases the moment of inertia of the clay. According to the law of conservation of angular momentum, the angular velocity of an object decreases when its moment of inertia increases.
An example to understand this is to think of a spinning ice skater. When the skater brings their arms closer to their body, their moment of inertia decreases and their angular velocity increases. Similarly, when the skater extends their arms outward, their moment of inertia increases and their angular velocity decreases.
