Final answer:
The impact force experienced by the fly and the bus is not the same due to the difference in mass between them. The acceleration experienced by the fly is greater due to its lower mass.
Step-by-step explanation:
When a fly collides with the windshield of a fast-moving bus, the impact force experienced by the fly and the bus is not the same. According to Newton's third law of motion, the force on the fly and the force on the bus are equal in magnitude but opposite in direction. However, due to the difference in mass between the fly and the bus, the accelerations experienced by them are different.
The acceleration can be calculated using the formula F = ma. Since force is equal for both the fly and the bus, the acceleration of the fly would be much greater compared to the bus due to its lower mass. This means that the fly will experience a much larger change in velocity and direction compared to the bus during the collision.
