Model rocket engines are rated by the impulse that they deliver when they fire. a particular engine is rated to deliver an impulse of 3.5 kg⋅m/s. the engine powers a 120g rocket, including the mass of the engine. part a what is the final speed of the rocket once the engine has fired? (ignore the change in mass as the engine fires and ignore the weight force during the short duration of the engine firing.)
