How to determine tension in the string on both sides of the pulley?

Question

anonymous · Answer

you'll need to give us the diagram though. the diagram is the clue.

ok so i figured it out but maybe you can help me find a final velocity instead? haha

anonymous · Answer

lol alright

anonymous · Answer

okay so i have the equation 1/2m2vf^2 + 1/2m1vf^2 + 1/2Iwf^2 - m1gd + ukm2gd

anonymous · Answer

im trying to find vf (the final velocity) after moving a distance d = .700 m

anonymous · Answer

it's best if we got the original question though lol
I'm guessing it will get easier if we apply the work-kinetic energy theorem

anonymous · Answer

1/2Iwf^2 being?

anonymous · Answer

final angular velocity

anonymous · Answer

and I is the inertia

anonymous · Answer

so the thing on top there equals?

anonymous · Answer

the total energy of the system

anonymous · Answer

no number?

anonymous · Answer

i dont think so

anonymous · Answer

oh! so you set the energy equations equal to each other! and then solve for vf?

anonymous · Answer

yup, I think. You've got two eqs equalling the same thing? then yeah. you should. lol

anonymous · Answer

okay let me try that! :)

anonymous · Answer

good luck :)

anonymous · Answer

thanks :)

anonymous · Answer

you're welcome :)

anonymous · Answer

okay it didnt work out with only vf ...crap this is awesome

Tension is the same on both sides of a mass less and frictionless pulley.

anonymous · Answer

yeah no im trying to find the final velocity after a distance d

these are examples

anonymous · Answer

no im not trying to find tension anymore but thanks :)
