A winch operates by means of a force applied by a rope. The winch is used to pull a load of mass $50\text{ kg}$ up a line of greatest slope of a plane inclined at $60^\circ$ to the horizontal. The winch pulls the load a distance of $5\text{ m}$ up the plane at constant speed. There is a constant resistance to motion of $100\text{ N}$ .

Find the work done by the winch.
