Energy, work and power — practice question
A block weighing $6.1\,\text{N}$ moves down a slope that makes angle $\tan^{-1}\left(\frac{11}{60}\right)$ with the horizontal. The coefficient of friction between the block and the slope is $\frac{1}{4}$. As the block goes through point $A$, its speed is $2\,\text{m s}^{-1}$.
