What Are the Speeds of the Fragments from a Space Rocket Explosion?

Click For Summary
SUMMARY

The forum discussion focuses on the conservation of momentum in a scenario where a rocket ship explodes into three equal mass pieces. One piece travels upward at 150 m/s, prompting the need to calculate the speeds of the other two pieces. Participants emphasize the importance of writing momentum equations for both the x and y directions, assuming no motion in the z direction. The discussion concludes that understanding these equations is crucial for solving the problem accurately.

PREREQUISITES
  • Understanding of basic physics concepts, specifically momentum conservation.
  • Familiarity with vector components in two-dimensional motion.
  • Knowledge of equations of motion in physics.
  • Ability to apply mathematical equations to physical scenarios.
NEXT STEPS
  • Study the principles of conservation of momentum in explosions.
  • Learn how to resolve vectors into their components in two dimensions.
  • Practice solving problems involving momentum conservation in various scenarios.
  • Explore the concept of impulse and its relationship with momentum.
USEFUL FOR

Students studying physics, educators teaching momentum concepts, and anyone interested in understanding the dynamics of explosive events in space.

Homework Statement


A rocket ship parked at rest in space suddenly explodes into 3 pieces of equal mass traveling in the directions shown. If the piece traveling upward has a speed of 150 m/s, what are the speeds of the other two pieces?

Homework Equations


The Attempt at a Solution


How do I conserve the momentum in this case? I'm clueless.

I think you mean conserve momentum.
Can you say anything about horizontal momentum?
