Energy, work and power — practice question
An object of mass $8\,\text{kg}$ moves down the line of greatest slope on an inclined plane. At the top of the plane, its initial speed is $3\,\text{m s}^{-1}$, and at the bottom its speed is $8\,\text{m s}^{-1}$. The work done against the resistance to motion of the object is $120\,\text{J}$.
