The incorrect attempt at a solution used the net force and total work done, instead of just the work done by the engine. The problem can be solved by using the conservation of energy equation, which states that the work done by non-conservative forces must equal the change in potential ...

That is, the fact that the vector product of two four-vectors is invariant leads to conservation of energy. In special relativity, there is a special frame of reference for massive objects known as the rest frame; in that frame p=0, so the relativistic energy equation is E=mc2, a ...
So now all of our mechanical energy is now kinetic energy. To calculate this, we're going to have to figure out what this v final is, and I'm going to go ahead and just give you the shortcut. This really just comes down to a vertical motion equation. So we're just going to...
from here I subbed into my conservation of energy equation for when the balls first make contact to when they have separated, I'm not quite sure what to do now, I don't think I can solve this since I have too many unknowns. Last edited: Sep 23, 2014 Physics news on Phys.org ...

So let's write the first one which is the energy equation from to . work non-conservative between and is . There is no kinetic energy at the top of the first hill because it's initially at rest. There's potential energy because it has height. There's no work non-conserv...
In special relativity, there is a special frame of reference for massive objects known as the rest frame; in that frame p=0, so the relativistic energy equation is E=mc2, a rather widely known result. All massive objects have energy by virtue of possessing mass, known as mass-energy. ...
