Final answer:
The object with the most inertia is the dump truck stopped at a red light, as inertia is proportional to mass and the dump truck has the largest mass of the objects listed.
Step-by-step explanation:
The object with the most inertia is the one with the greatest mass since inertia is a measure of how difficult it is to change an object's state of motion or rest and is directly proportional to the object's mass. So, among the options provided:
- A dump truck stopped at a red light
- A 100 kg piece of debris from the space station orbiting the earth at speeds over 1000 m/s
- A baseball flying towards home plate at 98 mi/hr
- A small Volkswagen Bug traveling on a neighborhood street
The dump truck has the most inertia because it has the largest mass.
