Suppose you want to design and market a faster yo-yo. That is, you want to make a yo-yo that will have a higher speed than that found in Example 9.3. How could you do it?

(a) Make the yo-yo radius larger.

(b) Make the yo-yo radius smaller.

(c) Add mass near the axis so that the yo-yo is shaped more like a sphere.

(d) Hollow out the center so that the yo-yo is shaped like a cylindrical shell.
