## Homework Statement

I have a 30kg crate on a flat floor. There is a rope pulling the crate to the right with a force of 125N. The coefficients of static and kinetic friction are .34 and .24 respectively. I need to know what the minimum force I could put on top of the crate to stop it from moving.

Fg = 9.81 m/s^2

uS = .34

uK = .24

m = 30kg

## Homework Equations

I know that I need to use Newtons second law to determine the sum of all forces in each direction, and see how much needs to be added to overcome the 125N pull. But honestly I have no idea where to start!

## The Attempt at a Solution

I know that Fg on the crate is 294.3N. And I know that friction opposes the way the crate is being pulled. But I really don't know how to piece this problem together.

Can anyone help?
