Homework Statement
The Gravitational binding energy of an object consisting of loose material, held together by gravity alone, is the amount of energy required to pull all of the material apart, to infinity. the gravitational binding energy Ug is roughly given by GM^2/R. how fast do you have to smash two neutron stars to get sufficient energy to unbind them?
Homework Equations
I honestly don't know where to start. I believe my teacher is asking for the velocity and then get the energy? also what formula should I use?
The Attempt at a Solution
im thinking we use Ug=Gm^2/R and use Ug= -GMm/r and have r= Tv/2pi
