Q1Energy, Work and PowerFree sample

A particle of mass $0.4\text{ kg}$ is projected with a speed of $12\text{ m s}^{-1}$ up a line of greatest slope of a smooth plane inclined at $30^{\circ}$ to the horizontal.

(i)

Find the initial kinetic energy of the particle.

(ii)

Use an energy method to find the distance the particle moves up the plane before coming to instantaneous rest.
