Kinematics of motion in a straight line — practice question

A $10\,\text{kg}$ block is initially stationary on a rough plane tilted at $30^\circ$ to the horizontal. A $120\,\text{N}$ force acts on the block at an angle of $20^\circ$ above the line of greatest slope (see diagram). A force opposes the block’s motion, and $200\,\text{J}$ of work is done against this force as the block moves $5\,\text{m}$ up the plane from rest.
