Exam points

  • Calculate tensions in vertically suspended bodies connected by light ropes.
  • Determine tension in an inclined system by resolving the component parallel to the slope and accounting for friction.
  • Infer how string angle controls the tension needed to provide a fixed vertical component, especially for nearly horizontal supports.
  • Apply Newton’s second law to find tension between connected blocks moving with friction or a shared acceleration.

IB Physics HL A 2 8 Tension Questions question 1

[Maximum number: 2]

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∘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.
