Re: [Phys-l] Conservation of energy in nuclear reactions

Thanks Brian - It apprears that if v(arr)=0, then v(dep)=2V, which was my crude understanding of what "slingshot" meant.

Stories on gravity assist seem to vary between the over simplified and
the over elaborated. Perhaps it would take a Russian to do it justice.
At any rate, this treatment from Columbia seems more careful than most....
