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 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
