I have seen a question about two bodies left in a free space and the question ask when shall they collapse.
For solving this I reached this step:(GM)*r^-2)*dr=(M*(m+M)^-1)*v*dv
For the left side,the lower bound of the integral is R and the upper bound is 0.after calculating it the answer of the left side is:1*0^-1-(GM*R^-2),what can we do with it?
