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?
1.0.5 N
2.2 N
3.8 N
4.0 N
According to Newton's third law of motion, for every action, there is an equal and opposite reaction. Therefore, the fence will exert a reaction force on the chair that is equal in magnitude but opposite in direction to the force exerted by the chair on the fence.
In this case, the wind blows the chair into the fence with a force of 8 N. So, the fence will exert a reaction force of 8 N on the chair in the opposite direction.
Therefore, the answer is 3. 8 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.
In this case, the force applied by the wind on the lawn chair is the action, and the reaction force exerted by the fence on the chair is equal in magnitude but opposite in direction.
Since the force applied by the wind on the chair is 8 N, the reaction force exerted by the fence on the chair will also be 8 N.
Therefore, the correct answer is:
3. 8 N
To determine the reaction force exerted by the fence on the chair, you can use Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. Therefore, the force exerted by the fence on the chair will be the same magnitude as the force exerted by the chair on the fence, but in the opposite direction.
In this case, the wind blows the lawn chair into the fence with a force of 8 N. So the fence will exert a reaction force of 8 N on the chair, but in the opposite direction.
Therefore, the correct answer is 3. 8 N.
