Which one of Newton's laws is this equation from and why?

a=[(m1-m2)g]/[m1+m2]

marshall4,
sorry but I think any law in physics has the form "If...then...".
Could you please explain what your symbols mean, i.e. what physical situation this equation describes? Thanks.
 
It comes from the action reaction law and the a=F/m law.
 
That would be Newtons second law. Force is proportional to and in the same direction as acceleration and inversial propotional to mass.
