## Homework Statement

## Homework Equations

F = ma

Fk= u * Fn

## The Attempt at a Solution

By analyzing the forces into components and applying Newton's second law

Fnet on y-axis = 0

So, Fn = mg + F2sin37 - F1sin 37 = 20 + 9 = 29 N

on x-axis

F = ma

F1 cos 37 + F2 cos 37 - Ffr = ma

F1 cos 37 + F2 cos 37 - uK * Fn = ma

5*0.8 + 20*0.8 - 0.2*29 = 2a

4 + 16 - 5.8 = 2a

14.2 = 2a

a = 7.1 m/s2Can you guide me to know my mistake, please?

Thanks in adavance
