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?
8 N
2 N
0 N
0.5 N
0 N
The reaction force that the fence exerts on the chair can be determined using Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
According to the given information, the wind blows the lawn chair into the fence with a force of 8 N. Therefore, the reaction force exerted by the fence on the chair is also 8 N.
So, the correct answer is 8 N.
To determine the reaction force exerted by the fence on the chair, we can apply Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction.
In this case, the force exerted by the wind on the chair (8 N) is the action, and the reaction force exerted by the fence on the chair is the force we need to find.
According to Newton's Third Law, the reaction force will be equal in magnitude but opposite in direction to the action force. Therefore, the reaction force exerted by the fence on the chair will also be 8 N.
So, the correct answer is 8 N.
