i'm surprised it hasn't been said, but a front brake (between the two) supplies about 70% of your total braking power, the rear supplies 30%. the same is true of all vehicles, which is why cars, even high end sports cars, have huge front rotors and small (in comparison) rear rotors.
imho you (most anyone) won't be able to stop efficiently with just a rear brake. you are much more likely to just run into what you are trying to avoid while running a rear brake than flipping over your bars running a front brake.

Specifically...the frictional force is the normal force multiplied by the coefficient of friction. When the bicycle decelerates quickly, the normal force decreases on the rear tire and increases on the front. This means that friction, and thus braking power, becomes much greater on the front tire and much smaller on the rear.
