Question

collision forces quick check
the wind blows a lawn chair that weighs 4 kg into a fence with a force of 8 n. how much reaction
force does the fence exert on the chair? (1 point)
2 n
0.5 n
0 n
8 n

Explanation:

According to Newton's third law of motion, for every action, there is an equal and opposite reaction. The chair exerts a force of 8 N on the fence (action), so the fence exerts an equal force of 8 N on the chair (reaction). The mass of the chair (4 kg) is irrelevant to finding the reaction force in this context as Newton's third law focuses on the interaction between two objects (here, chair and fence) and their force pairs.

Answer:

8 N (the option corresponding to 8 N in the given multiple - choice list)
