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. A thruster exerts a force of 25 kN for 2.0 minutes in the opposite direction of motion. The initial momentum is calculated using the formula p = mv, resulting in 1.2 x 107 kg·m/s. The final momentum can be determined by applying the impulse-momentum theorem, which states that impulse equals the change in momentum.

PREREQUISITES
  • Understanding of momentum and its formula (p = mv)
  • Knowledge of impulse and its relation to momentum
  • Basic physics concepts related to force and motion
  • Ability to perform unit conversions and calculations involving time and force
NEXT STEPS
  • Study the impulse-momentum theorem in detail
  • Learn about the effects of continuous forces on momentum
  • Explore the concept of force over time and its impact on motion
  • Practice solving problems involving momentum calculations in different scenarios
USEFUL FOR

Physics students, educators, and anyone interested in understanding momentum calculations and the effects of forces on moving objects.

Homework Statement


a 1.0*10^4kg spacecraft is traveling through space with a speed of 1200 m/s realtive to earth. a thruster fires for 2.0 min, exerting a continuous force of 25kN on the spacecraft in a direction opposite the spacecraft s motion . calculate the initial momentum and the fianl momentum kof the spacecraft .

I have found a clever and elegant solution, but it is too long for this post to contain.
 
Note: My response was sarcastic, since when I posted it you hadn't yet included the problem statement! Sorry for any confusion.

Do you know the formula that defines momentum? That should give you the initial momentum pretty easily. As for the final momentum, there are multiple ways of finding it, but they probably want you to use the fact that impulse is equal to change in momentum.
