comment Could heavy-lift ships be used as oil tankers to stop oil spills?
I tried to edit your question for brevity. Is it still faithful to your question?

comment Why are some surfaces slippery?
@harogaston I agree. It isn't a complete duplicate, so I thought I'd leave it up to the OP.

comment The fundamental equations of electromagnetism
@RyanL Would it always be possible to do so, however? For example, in a system with charges moving with different velocities, there would be no single frame for which all charges are stationary.

comment The fundamental equations of electromagnetism
In addition, Coulomb's Law doesn't apply for moving charges.

comment Figuring out the time period of an Atwood system
This seems like quite a complex problem to solve analytically without Lagrangian mechanics, unless I'm missing some technique; I'd encourage you to take a numerical approach. You state that this is a simplified version of another problem - what was that problem? It may be easier to solve.

comment Figuring out the time period of an Atwood system
First, your second equation isn't correct if the string is moving along the pulley wheel, since mass $m_2$'s motion wouldn't be circular. Second, you'll probably need to solve a differential equation to determine the total motion -- are you familiar with differential equations?

That's quite true.

comment What is the best path for a given initial and final state?
The problem with a cubic fit is that it often results in funny motion. For example, the objects may sometimes move backwards, which the OP doesn't want.
