Elastic Collisions solving for velocity any help?

Click For Summary
SUMMARY

The discussion focuses on solving for the final velocities (m1v1f and m2v2f) in elastic collisions using the equations of motion. The key equations presented are the conservation of kinetic energy and momentum: 1/2m1v1,0 = 1/2m1v1f^2 + 1/2m2v2f^2 and m1v1,0 = m1v1f + m2v2f. A suggestion is made to simplify the problem by dividing everything by m1 and squaring the second equation to facilitate the solution.

PREREQUISITES
  • Understanding of elastic collision principles
  • Familiarity with conservation of momentum and energy equations
  • Basic algebra skills for manipulating equations
  • Knowledge of variables in physics (masses and velocities)
NEXT STEPS
  • Practice solving elastic collision problems using different mass and velocity scenarios
  • Explore the derivation of the elastic collision equations in detail
  • Learn about inelastic collisions and how they differ from elastic collisions
  • Investigate real-world applications of elastic collisions in physics and engineering
USEFUL FOR

1/2m1v1,o=1/2m1v1f^2 +1/2m2v2f^2
and
m1v1,0= m1v1f + m2v2f

any idea on how to solve for m1v1f and m2v2f

Hi bigred22! Welcome to PF! :smile:

(try using the X2 and X2 tags just above the Reply box :wink:)

Try dividing everything by m1, and squaring the second equation. :wink:
