SUMMARY

The discussion centers on solving a physics problem involving momentum conservation after a bomb explodes into three equal mass pieces. Two pieces have velocities of (12i + 24j) m/s and (30i - 24j) m/s. By applying the principle of conservation of momentum, the speed of the third piece can be determined using the equation m1v1 + m2v2 + m3v3 = 0, since the bomb starts at rest. The total momentum of the system must equal zero, leading to a straightforward calculation for the third piece's velocity.

PREREQUISITES
  • Understanding of momentum conservation principles
  • Familiarity with vector addition in physics
  • Basic knowledge of kinematics
  • Ability to solve equations involving multiple variables
NEXT STEPS
  • Study the concept of momentum in two dimensions
  • Learn about vector decomposition and addition
  • Explore examples of conservation of momentum in explosions
  • Practice solving similar physics problems involving multiple objects
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and momentum, as well as educators looking for examples of conservation laws in action.

Homework Statement



A bomb that is originally at rest blows apart into three pieces of equal mass. Two of the
pieces have velocities (12i + 24j) m/s and (30i - 24j) m/s. What is the speed of the third
piece?

Homework Equations



m1v1 + m2v2 + m3v3 = 3mv4 (assuming m is the same)


The Attempt at a Solution



Not really sure where to begin. I can find the speed of the 2 objects by finding the k direction, but that's it.
