Model rockets are lightweight rockets powered by very small engines. A typical model rocket has a mass of 5g.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 launched this rocket horizontally, how fast would it be going in m/s after the engine burns out?

Question

Damon · Answer

Force = mass(change in speed/change in time) impulse = force*time = mass (change in speed) 10 = .005 ( v ) v = 10 /5*10^-3 = 2*10^3 = 2,000 m/s
