Normal Force Problem: Calculating Magnitudes

[johnson.3131]

Homework Statement

A 41 kg crate rests on a horizontal floor, and a 53 kg person is standing on the crate.

(a) Determine the magnitude of the normal force that the floor exerts on the crate.


(b) Determine the magnitude of the normal force that the crate exerts on the person.

Homework Equations

The Attempt at a Solution

Normal force is usally the opposite of weight so i converted the kg to Newtons and thought maybe that was the answer?

Welcome to PF.

Yes force is in Newtons. And Normal force is what the stuff on top of it weighs right?

So How much do the crate/guy weigh on te floor and how much does the guy weigh on the crate?
