Asa 500n woman sits on the floor, the floor exerts on her a force of?

500 N

Explanation:

The woman is sitting on the floor, this means that she is in equilibrium: therefore, her acceleration is zero (a=0), so according to Newton's second law

F = ma

the net force acting on her (F) must also be zero.

There are only two forces acting on the woman:

- The force of gravity (also called weight, W), acting downward, of magnitude 500 N

- The normal reaction exerted by the floor on her, N, acting upward

So the equation of the forces for the woman is

Since the net force is zero.

From the equation, it follows that

So, the floor exerts 500 N of force on the woman.
