Use conservation of energy to determine the angular speed of the spool shown in the figure below after the 3.00 kg bucket has fallen 4.40 m, starting from rest. The light string attached to the bucket is wrapped around the spool and does not slip as it unwinds.
I initially thought this would be a simple plug and chug problem but it turns out I was wrong...
This is where I kind of got stuck and so I kind of freestyled... -.-
Iωinitial = Iωfinal
(3)(0.6002)ω = (3)(4.402)ω
1.8ω = 58.08ω
-.-
Help?
