AI Thread Summary
The discussion focuses on calculating the tension in a vine when Jill, who weighs 61 kg, swings at a speed of 2.6 m/s. The relevant equation for tension in circular motion is F=mv^2/r, which accounts for both centripetal force and gravitational weight. Participants express confusion about setting up the equation and understanding the components of tension when Jill is both hanging and moving. Clarification is provided that total tension is the sum of tension from centripetal force and the weight of Jill. The conversation highlights the challenge of grasping circular motion concepts in physics.

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! -_-

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
