## Homework Statement

A force of 20N,180degrees (W) and 30N,-110degrees (S20degrees (W) ) are both acting on a 3.0kg mass at rest. If there is 10N of friction:calculate the acceleration.

## Homework Equations

I think you just need kinematic equations so here they are:

V2=V1+a*t

d=V1t+1/2a*t^2

## The Attempt at a Solution

Im going to try the R theta and change that to x and y I just wanted to put this up first stop me if this is wrong.
