## Homework Statement

What is the minimum horizontal force F needed to make the box start moving in (Figure 1) ? The coefficients of kinetic and static friction between the box and the floor are 0.25 and 0.46, respectively.

## Homework Equations

Fs= mu * N

## The Attempt at a Solution

So I know that the normal force is 432 N because of the additional force acting on the 28kg object. The angle is throwing me off a little bit. Since I am only finding the horizontal force would I only take into account cos(55)?
