Model Rockets Can Go Pretty Fast

Model rockets are lightweight rockets powered by very small engines. A typical model rocket has a mass of 50 grams. Similarly, a typical "class C" model rocket engine can produce a total impulse of 10 Newton-seconds. We usually launch model rockets vertically, but if I instead launch this rocket horizontally, how fast would it be going in m/s after the engine burns out?
