A child pushes a desk with a force of 15 N to the right. The desk accelerates to the right. Which of the following statements correctly represents Newton’s third law and the interaction between the child and desk?
Responses
The desk exerted slightly more than 15 N of force on the child, but the force is directed to the left.
The desk exerted slightly more than 15 N of force on the child, but the force is directed to the left.
The desk exerted exactly 15 N of force on the child, but the force is directed to the left.
The desk exerted exactly 15 N of force on the child, but the force is directed to the left.
The desk did not exert any force on the child.
The desk did not exert any force on the child.
The desk exerted slightly less than 15 N of force on the child, but the force is directed to the left.
None of the above statements correctly represent Newton’s third law and the interaction between the child and desk. According to Newton's third law, for every action, there is an equal and opposite reaction. In this scenario, the child is exerting a force of 15 N on the desk, and the desk will exert an equal and opposite force of 15 N on the child (directed to the left). Therefore, the correct statement would be: The desk exerted an equal and opposite force of 15 N on the child, directed to the left, according to Newton's third law.
equal and opposite cancels out to 0
Equal and opposite forces do not cancel out to zero since they act on different objects. In this scenario, the child exerts a force of 15 N on the desk, and the desk exerts an equal and opposite force of 15 N on the child. These forces are acting on different objects (child and desk) and thus do not cancel out to zero. Instead, they create an interaction force pair according to Newton's third law. The force acting on the desk causes it to accelerate to the right, while the force acting on the child causes them to move slightly to the left due to the reaction force.
if u had to choose one given answer which one would u pick
If I had to choose one of the given answers, I would choose "The desk exerted an equal and opposite force of 15 N on the child, directed to the left, according to Newton's third law." This statement accurately represents Newton's third law and the interaction between the child and the desk. The other options given do not accurately represent the situation described.
The correct statement that represents Newton's third law and the interaction between the child and desk is: The desk exerted exactly 15 N of force on the child, but the force is directed to the left.
To determine the correct statement, we need to apply Newton's third law: "For every action, there is an equal and opposite reaction."
In this scenario, the child is pushing the desk with a force of 15 N to the right. According to Newton's third law, the desk exerts an equal and opposite force on the child. Therefore, the force exerted by the desk on the child is also 15 N.
Now, let's consider the direction of the force. The child pushes the desk to the right, so the desk exerts a force on the child in the opposite direction, which is to the left. Therefore, the correct statement is:
The desk exerted exactly 15 N of force on the child, but the force is directed to the left.
