Is this right?, conservation of energy

AI Thread Summary
The discussion revolves around applying the conservation of energy and momentum principles to a physics problem involving a water tank. Participants explore whether the tank moves in the negative x-direction when water is released, with some arguing that the tank should maintain a constant velocity due to the frictionless surface. The concept of center of mass is debated, particularly regarding how it affects the tank's motion and whether the final velocity of the tank can be zero. There is also a focus on deriving equations for the tank's motion and the distance traveled by the water. Overall, the conversation emphasizes understanding the implications of conservation laws in this context.

It can still be cleaned up some. Drop the zero and use the fact that -ln(b/a) = +ln(a/b).

Ok so I have now

R = L (ln(M/M-m)) = x

That looks much neater.
