Energy, work and power — practice question
The winch works through a force applied by a rope. It is used to haul a load of mass $50\,\text{kg}$ along the line of greatest slope of a plane that is inclined at $60^\circ$ to the horizontal. The winch moves the load a distance of $5\,\text{m}$ up the plane at constant speed. A constant resistance to motion of $100\,\text{N}$ acts.
