Final answer:
The relationship between the mass of the object and the initial speed required to hit a target is inversely proportional.
Step-by-step explanation:
The relationship between the mass of the object and the initial speed necessary to hit a target can be described as inversely proportional. This means that as the mass of the object increases, the initial speed required to hit the target decreases. Conversely, as the mass of the object decreases, the initial speed required to hit the target increases.
For example, if you are throwing a baseball at a target, a lighter baseball will require a higher initial speed to hit the target, while a heavier baseball will require a lower initial speed.
Therefore, the correct answer is option b) Inversely proportional.
