SUMMARY
The discussion revolves around calculating the final velocity of a model rocket after expelling fuel, utilizing the principle of conservation of momentum. A 4.00 kg rocket expels 63.0 g of fuel at a speed of 565 m/s. The correct approach involves setting up the momentum equation as (rocket mass × initial velocity) + (fuel mass × fuel speed) = (rocket mass × final velocity) + (fuel mass × (fuel speed - final velocity)). The final velocity of the rocket after the fuel has burned is determined to be 8.89 m/s.
