IB Physics HL A 2 8 Tension Questions

Practise analysing HL tension systems with multiple ropes, friction and inclined motion.

Exam points

Identify tension as the pulling force transmitted through a taut string, cable or rope, acting along its length.
Determine tension in connected-body systems from complete free-body diagrams, equilibrium or motion equations and mark-scheme evidence.

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 $12^{\circ}$ 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.

tension = frictional force + component of weight parallel to slope /
tension $=65+m g \sin \theta$ ;
$214 / 210 \mathrm{~N}$ ;
