Aha, got it! I knew the initial problem had to do with my initial potential energy, so I realized I could set it equal to:
PE = mh*g(0.8/1.2)
As the initial acceleration is dependent upon the ratio of mass at any given end and gravity. Using this, I could go straight to kinetic energy and...
Homework Statement
A limp rope with a mass of 2.5 kg and a length of 1.2 m is hung, initially at rest, on a frictionless peg that has a negligible radius. The rope is hung such that 0.8m hangs off the longer end, and 0.4m off the lower end. What is the vertical velocity of the rope just as...
