Exam points
- draw tension away from a body along the string and resolve components on an incline

- distinguish the tension in each string when connected bodies or friction differ
A.2.8—Tension question 1
This question is about the forces on a skier.
A skier is pulled up a hill by a rope at a steady velocity. The hill makes an angle of with the horizontal. The mass of the skier and skis is 73 kg . The diagram below shows three of the forces acting on the skier.
The total frictional force acting is 65 N . Determine the tension in the rope.
