Q13MEnergy, Work and PowerFree sample

A particle of mass $0.6\text{ kg}$ is projected with a speed of $4\text{ m s}^{-1}$ down a line of greatest slope of a smooth plane inclined at $10^{\circ}$ to the horizontal.

Use an energy method to find the speed of the particle after it has moved $15\text{ m}$ down the plane.
