The force on the grass hopper is equal and opposite to the force on the wind shield.
Explanation:
It is a known fact every action has an equal and opposite reaction. Here the action force is the grasshopper hitting the windshield.
The reaction force is the force exerted by the windshield on the grasshopper.
