A skier is pulled up a hill by a rope at a steady velocity. The hill makes an angle of 12˚ with the horizontal. The mass of the skier and skis is 73kg. The diagram below shows three of the forces acting on the skier.

(a) On the diagram, predict the direction of any other force acting on the skier.

(c) The total frictional force acting is 65N. Determine the tension in the rope.
