Answer:
The box with the most inertia is the one with a mass of 6kg (Option D).
Step-by-step explanation:
The inertia of an object is directly proportional to its mass. Inertia refers to an object's resistance to changes in its state of motion, whether that be a change in speed or direction. Therefore, the greater the mass of an object, the greater its inertia.
In your list, the order of inertia from least to most would be:
A) 3kg (least inertia)
B) 4kg
C) 5kg
D) 6kg (most inertia)
So, the box with the most inertia is the one with a mass of 6kg (Option D).
