A person pushes a box on a rough horizontal platform surface. He applies a force of $200 \mathrm{~N}$ over a distance of $15 \mathrm{~m}$. Thereafter, he gets progressively tired and his applied force reduces linearly with distance to $100 \mathrm{~N}$. The total distance through which the box has been moved is $30 \mathrm{~m}$. What is the work done by the person during the total movement of the box ?
Consider a force $\vec{F}=-x \hat{i}+y \hat{j}$. The work done by this force in moving a particle from point $\mathrm{A}(1,0)$ to $\mathrm{B}(0,1)$ along the line segment is: (all quantities are in SI units)
