Forces and equilibrium — practice question

A block with mass $12\,\text{kg}$ is pulled upward by a rope on a rough plane. The plane makes an angle of $20^\circ$ to the horizontal. The rope acts parallel to the line of greatest slope of the plane. The coefficient of friction between the block and the plane is $0.4$. The block’s acceleration is $2\,\text{m s}^{-2}$.
