Ana exerts a force of 20 n on a volleyball that has a mass of 0.15 kg what is the force that the volleyball exerts on ana

Answer

The volleyball should exert the same 20 N on Ana.

Explanation

The 3rd Newton's law of motion states that, for any action, there is an equal and opposite force.

This means a body placed on top of a table exerts a force, say X N, on the table. For the table to hold that body it  must be exerting an equal force (X N) to the body.

∴ If Ana exerts a force of 20 N on the volleyball, the volleyball should exert the same 20 N on Ana.
