Centripedal force velocity question.

Click For Summary

Homework Help Overview

The problem involves Tarzan swinging from a tree using a vine, with a focus on determining his velocity at the bottom of the swing. The subject area pertains to concepts of energy conservation and dynamics in a gravitational field.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the relevance of mass in the context of energy conservation and explore the relationship between potential and kinetic energy during the swing.

Discussion Status

Some participants have offered hints regarding conservation principles, while others are actively questioning the assumptions about mass and energy. There appears to be a productive dialogue around the initial and final energy states of the system.

Contextual Notes

The original question lacks specific information about mass, which has led to discussions about its necessity in solving the problem. Participants are also considering the implications of height changes during the swing.

Tarzan is standing on a limb of a tree, holding onto a vine whose length is 30 m. Seeing Jane on a branch of another tree, Tarzan decides to use the vine to swing oer to Jane's branch. The vine he is holding onto makes an angle of 37 degrees with the horizontal. What will be Tarzan's velocity at the bottom of his swing toward Jane?

the question doesn't give you a mass, i have no clue how to do it
any help is appreciated thanks!

You don't need to know the mass. (Just call it "m" and continue.)

Hint: What's conserved?
 
what is conserved?? I am guessing you mean energy. so if i use the equation final energy = initial energy with all the mass canceling out and then i find the height of tarzan in the middle of his swing in relation to tarzan at the beginning of his swing, i should be able to calculate the final velocity, correct?
 
Sounds to me like you've got it.
