Answer: the force of impact is the same in magnitude for both the winshield and the bug, and in opposed directions.
Explanation:
1) Whenever two objects are in contact you have to think about the Third Law of Newton, named action-reaction force.
2) According to this law, action and reaction have the same magnitude but opposite directions.
3) Think that forces always come in pairs. They act over different objects, have the same magnitude and act on opposite directions. Some additional examples are:
i) When you kick a stone, the force of your foot on the stone is the same force of the stone on your foot.
ii) When you stand on the ground, the force that your feet exert on the ground is equal to that that the ground exerts on you feet, but in opposite direction.
iii) When you push a block, the block pushes you with the same magnitude.
