Homework Statement
A rope of mass M and length L lies on a frictionless table, with a short portion L0 hanging through a hole. Initially the rope is at rest. Evaluate A and B so that the initial conditions are satisfied.
The Attempt at a Solution
Ok, so I understand the problem and have gotten the final 2 equations (according to my book):
yAeyt-yBe-yt=0
L0=Aeyt+Be-yt
It looks like, according to the first equation, Be-yt=Aeyt. Plugging this into the second equation, L0=2Aeyt and L0=2Be-yt. This seems intuitively wrong, but I'm not sure exactly why. Any thoughts?
