Homework Help Overview

The problem involves determining the tension in a vine when a person swings on it, specifically focusing on the dynamics of circular motion. The context includes the mass of the person and their velocity at a specific point in the swing.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants discuss the tension in the vine both when the person is stationary and when in motion, questioning how to set up the equations for these scenarios. Some express confusion about applying concepts from circular motion to this problem.

Discussion Status

The discussion includes attempts to clarify the components of tension in different scenarios, with some participants expressing uncertainty about the setup of the equations. There is acknowledgment of the need for further exploration of the concepts involved.

Contextual Notes

Some participants mention feeling overwhelmed by the lack of examples in their resources related to circular motion, indicating a potential gap in understanding the application of the concepts to this specific problem.

Homework Statement


Jill of the Jungle swings on a vine 6.6 m long. What is the tension in the vine if Jill, whose mass is 61 kg, is moving at 2.6 m/s when the vine is vertical?

Homework Equations


F=mv^2/r

The Attempt at a Solution


F=(61)(2.6^2)/6.6

When Jill is just hanging on a vine, what is the tension in the vine?
When Jill is moving with a velocity, what additional tension is added to the vine?

I'm sorry I still do not understand how to go about setting up the equation...I tried going over examples in my book for this type of circular motion but there does not seem to be any so I am beyond confused...I know that once I figure it out I will feel completely stupid but for now, I am just stumped. -_-
 
Total tension = tension due to centripetal force + tension due to weight.
 
thank you SOOOO much...i'm such an idiot! -_-
