several cars (n) were involved in this collision, the input matrix (vm) has n rows and two columns, first column for velocity and second column for mass of each car. assume momentum conservation, output final velocity. Example -- vm=[60 2; -30 4], first car velocity (+60) mph, mass 2 tons; second car velocity (-30) mph, mass 4 tons, final velocity is zero.
20 is the best general solution. Lower scores take advantage of the limited test suite.
vm=[60 2; -30 4; 100 2]; velo is 200 not 25
The momentum is 200, not the velocity.

We love vectorized solutions. Problem 1 : remove the row average.
