SUMMARY
The discussion focuses on calculating the initial and final momentum of a spacecraft with a mass of 1.0 x 104 kg traveling at 1200 m/s when a thruster exerts a force of 25 kN for 2.0 minutes in the opposite direction. The key equations used include impulse, defined as J = Δp = pf - pi, and the conversion of time from minutes to seconds, resulting in 120 seconds. The correct application of these principles leads to the determination of the spacecraft's momentum before and after the thruster firing.
