A block of mass $$m~kg$$ and length $$1~m$$ is placed on a horizontal rough surface having a variable kinetic friction coefficient. A horizontal force $$F$$ is applied such that the block moves slowly. What is the total heat released in the process? The coefficient of friction varies as follows: $\mu _ k = \cases{ x \quad \rm{for~0\le x \le 1} \\ 0 \quad \rm otherwise}$
