Kinematics of motion in a straight line — practice question

A block with mass $3\,\text{kg}$ is at rest at the start on a smooth horizontal floor. A force of $12\,\text{N}$, applied at an angle of $25^\circ$ above the horizontal, acts on the block.
(main)[4]

Determine the distance covered by the block during the first $5\,\text{s}$ of its motion.
