The question as text
A particle of mass 8 kg is projected with a speed of 5 m s−1 up a line of greatest slope of a rough plane inclined at an angle ! to the horizontal, where sin ! = 5 13. The motion of the particle is resisted by a constant frictional force of magnitude 15 N. The particle comes to instantaneous rest after travelling a distance x m up the plane.
