Question

1. a woman with a weight 500 n sits on the floor. assuming that there are no other external forces acting, she exerts a force on the floor of 500 n, how much force will the force exerts on her? how?

Explanation:

Step1: Apply Newton's third - law

According to Newton's third - law, for every action, there is an equal and opposite reaction. The woman exerts a force of 500 N on the floor (action).

Step2: Determine the reaction force

The floor will exert an equal and opposite force on the woman. So the force exerted by the floor on the woman is 500 N in the upward direction.

Answer:

500 N
