Question

Ana exerts a force of 20 n on a volleyball that has a mass of .15kg what is the force that the volleyball exerts on ana?

Answer 1

Ana exerts a force of 20N on the volleyball.

By Newton's third law, that for every action there is an equal and opposite reaction.

Therefore the volleyball exerts a force of -20N on Ana.  

Answer 2

Explanation: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,
