Margie, who weighs 590 N, is standing on a bathroom scale that weighs 38.0 N. With what magnitude force does the scale push up on Margie?With what magnitude force does the floor push up on the scale?

Respuesta :

Answer:

The scale pushes up on Margie: 590 N

The floor pushes up on the scale: 628 N

Explanation:

The free-body diagram for Margie and the scale is

Then, the magnitude force is equal to the normal force for each case.

For the first case, we get:

Fn = 590 N

For the second case, we get:

Fn = 590 N + 38 N = 628 N

So, the scale pushes up Margie with a force of 590 N and the floor pushes up on the scale with a force of 628 N.
