Final answer:
Without information about the wheelbase, we cannot determine the car's balance based on the center of mass alone, so the mass is irrelevant to its balance without additional context.
Step-by-step explanation:
The question you've asked is related to the concept of the center of mass in physics. When determining if a car is front-heavy or back-heavy, you need to consider the location of the center of mass relative to the wheelbase. If the center of mass is exactly in the middle of the wheelbase, the car is perfectly balanced.
However, without information about the entire wheelbase of the car, we cannot determine if the car is front-heavy, back-heavy, or balanced just based on the fact that the center of mass is 2.20 m behind the front of the car. Therefore, the correct option is D: The car's mass is irrelevant to its balance without more information.
The center of mass of an empty car can help determine whether the car is front-heavy or back-heavy. In this case, the center of mass of the car is located 2.20 m behind the front of the car. Since the center of mass is located behind the front of the car, it means that more weight is concentrated towards the back of the car. Therefore, the correct answer is B. The car is back-heavy.
Therefore, the correct option is D: The car's mass is irrelevant to its balance without more information.
