SUMMARY

In the discussion regarding Tarzan's swing from point A to point B, key calculations were made based on physics principles. Tarzan, with a mass of 100 kg, swings from a 10 m long vine at a 60-degree angle. The height difference between points A and B is calculated to be 1.34 m, and the work done by Earth's gravity during the swing is determined to be 4387.80 Joules. The discussion also addresses the speed of Tarzan at point B and the tension in the vine, which require further analysis.

PREREQUISITES
  • Understanding of basic physics concepts, including gravitational potential energy and kinetic energy
  • Knowledge of the conservation of energy principle
  • Familiarity with trigonometric functions to calculate height and angles
  • Ability to apply Newton's laws of motion to determine tension in a swinging object
NEXT STEPS
  • Calculate the speed of Tarzan at point B using conservation of energy principles
  • Determine the tension in the vine at point B using Newton's second law
  • Explore the effects of friction on swinging motion and how it alters calculations
  • Review the concepts of centripetal force in the context of swinging objects
USEFUL FOR

Physics students, educators, and anyone interested in understanding the dynamics of swinging motion and energy conservation principles in real-world scenarios.

Tarzan swinging on a vine...PLEASE HELP

starting from rest at point A, Tarzan (whose mass = 100kg) swings on a 10 m long vine, which initially makes a 60deg angle with with the vertical.

a) how much lower than the starting point A is Tarzan, when he reaches point B, the lowest part of his swing?
i got 1.34

b)how much work has Earth's gravity done on tarzan between points A and B
i got 4387.80Joules

c) how fast is tarzan moving at point B? neglect friction
> i don't understand how to approach this one
d) what is the tension in the vine when tarzan passes through point B?
> yeh don't know about this one either
