Answer:
The answer is choice C.
Explanation:
According to Newtons third law of motion, the force that object exerts on the child is equal and opposite to the force that the child exerts on the object:
[tex]F_{child}=-F_{object}[/tex]
Thus if the child exerts a force of 100 newtons on the object, the object must also exert a force of 100 newtons on the child but in the opposite direction.
The magnitude of the force the object exerts on the child is 100 N.
The given parameters;
- mass of the child, m = 40 kg
- force exerted by the child, F = 100 N
- mass of the object = 50 kg
According to Newton's third law of motion, for every action there is an equal and opposite reaction.
- The magnitude of the force the child exerted on the object is equal to the force the object exerted on the child.
- The direction of these forces are opposite.
Thus, the magnitude of the force the object exerts on the child is 100 N.
