SUMMARY

The discussion focuses on calculating the momentum of fragment 2 after an explosion, given that fragment 1 has a momentum of 23 kg·m/s at an angle of 28° RCS. The conservation of momentum principle is emphasized, indicating that the total momentum before and after the explosion remains constant. Participants suggest breaking down the momentum into x and y components using equations such as P = mv, Rx = Rcos∅, and Ry = Rsin∅ to solve for the unknown momentum of fragment 2.

PREREQUISITES
  • Understanding of conservation of momentum principles
  • Familiarity with vector decomposition into x and y components
  • Knowledge of basic physics equations related to momentum (P = mv)
  • Ability to interpret angles in relation to momentum calculations
NEXT STEPS
  • Study vector decomposition techniques in physics
  • Learn about conservation laws in explosive events
  • Explore momentum calculations in two-dimensional systems
  • Review examples of momentum conservation problems involving multiple fragments
USEFUL FOR

Students studying introductory physics, particularly those focusing on momentum and explosive dynamics, as well as educators seeking to enhance their teaching methods in these topics.

What is the momentum of fragment 2 after the explosion?

Homework Equations


PT=PT'
P=mv
Rx= Rcos∅
Ry= Rsin∅
R= √x2+y2

The Attempt at a Solution


This is all the information given. I haven't a clue at how to even begin with this one. We generally receive minimal instruction, and we haven't done a single problem like this one. Everything else was a stationary object exploding and we were given masses and velocities and times.

Do I break it down into x and y components and find out the momentum of the grey line, then use that, combined with the 21° (331°?RCS(no clue if that's right, seeing as he went out in left field the other day with the rcs)) to get the momentum of fragment 2? That's the only thing I can think of
 
Physics news on Phys.org
Vertical component of momentm is also conserved.
Try to find the relation connecting sine components of the two pieces.
 
I was just about to ask what a feynman diagram was doing in introductory physics, then I read the question :D

it's all conservation of momentum!
