Assuming the system is closed, which statement is correct about this system? A. Nina experiences a force equal to f. B. Nina experiences a force equal to f/2.

If the system is closed, Nina will experience only a force equal to F exerted by Jon.

According to Newton's third law of motion, action and reaction is equal and opposite. That is the force applied to a stationary object is equal to the reaction exerted by the stationary object.

Applying this law, the force Jon applied on Nina is equal to the reaction Nina exerts on Jon.

  • If Jon exerts a force of F magnitude on Nina, consequently, Nina will experience the force of equal magnitude and exert equal reaction in opposite direction towards Jon.
  • Also, if the system is closed, no additional force will be experienced by Nina, except the force applied by Jon.

Thus, assuming the system is closed, Nina will experience only a force equal to F exerted by Jon.
