## Homework Statement

A crate is placed on an inclined board. The coefficient of friction between the crate and the board is 0.26 , and the angle of the slope is 16 degrees. Calculate the acceleration of the crate down the incline.

## Homework Equations

F=ma

Ff=umgcos(theta)

Forge of gravity parallel = mgsin(theta)

## The Attempt at a Solution

F=ma

Fg - Ff = ma

mgsin(theta) - umgcos(theta) = ma

so this is where it gets tricky for me.. i've tried factoring and removing a mass from each side.. but i'm still left with one mass.

What do i do? :/
