Answer:

Explanation:

m = 55 kg

a = 9.8

F = ?

The first thing you are going to do is find the force that the girl represents.

F = 9.81 * 55

F = 539.55

But that is not the answer. That is her weight. A very important part of this question is to realize that the floor is pushing up on her with an equal force.

Her weight is going DOWN.

The floor is pushing UP with a force of 539.55 Newtons.
