The moment of inertia of a uniform rod about an axis through its center is M L 2 / 12. The moment of inertia about an axis at one end is M L 2 / 3. Explain why the moment of inertia is larger about the end than about the center.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
