A fly strikes the windshield of a moving truck as shown. What can you say about the forces: the force on the fly and the force on the truck.
- A. Force on the fly \( > \) Force on the truck
- B. Force on the fly \( < \) Force on the truck
- C. Force on the fly = Force on the truck
- D. None of thes
Step-by-step solution
According to Newton's third law of motion, the force exerted by the truck on the fly and the force exerted by the fly on the truck are an action-reaction pair; they are equal in magnitude and opposite in direction. Thus, the forces are equal.
