(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

At the instant shown, the block is moving down the slope. What is the acceleration up the slope if the kinetic coefficient of friction is 0.4? the relevant diagram is attached and shows a pulley with one end connected to a wall and the other end pulling with a force of 42N at an angle of 35 deg connected to a mass of 13 kg.

2. Relevant equations

3. The attempt at a solution

I've used F=u*mg*cos(A)-T*sin(B) and then used that to find a,

where a=(F+T+Tcos(B)-mgsin(A))/m and F=force of friction, T=tension in pulley, A=angle of incline, B=angle of tension.
