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
1. Which unit is used to measure force?
newton
2. A baseball collides with a baseball glove. Which equation is used to calculate the force the glove exerts on the ball during the collision?
force = mass × acceleration
3. A 0.2-kilogram softball is thrown toward a catcher’s mitt. The ball is accelerating at a rate of 8 meters per second squared. With what force will the ball hit the catcher’s mitt?
1.6N
4. A tennis player hits a 0.1-kilogram tennis ball with her racket from the north end of a court. Her racket was traveling at 65 kilometers per hour. The ball accelerated at a rate of 10 meters per second squared. The ball hits the floor on the south end of the tennis court. The floor sends the ball toward the tennis player's opponent with the same acceleration. How much force did the floor on the south end of the court exert on the ball?
1N
5. 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

Google Newton, third law
To find the reaction force exerted by the fence on the chair, we can use Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
In this case, the action is the force applied by the chair on the fence (8 N). 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 is also 8 N, but in the opposite direction.
