Final answer:
Both the bug and the car experience the same change in momentum because the law of conservation of momentum states that the total momentum of a system remains constant in the absence of external forces.
Step-by-step explanation:
When considering the question of who experiences the greater change in momentum after a collision between a bug and a car, it is important to understand the principle of conservation of momentum. The law of conservation of momentum states that in the absence of external forces, the total momentum of a system remains constant. Therefore, when the bug collides with the car, both the bug and the car experience equal and opposite changes in momentum. So, the answer is C) Both the bug and the car experience the greater change in momentum equally.
