Collision of multiple particles

Click For Summary
SUMMARY

The discussion revolves around solving a collision problem involving multiple particles, where the user believes the coefficient of restitution (e) should equal 1, while the provided answer is 2/3. Participants clarify that the method used by the user is only valid for two-particle collisions and emphasize the need for adjustments to apply it to multiple particles. The importance of momentum conservation for the entire system is highlighted, indicating that multiple lines of impact must be considered for accurate calculations.

PREREQUISITES
  • Understanding of collision physics, specifically the coefficient of restitution.
  • Knowledge of momentum conservation principles in physics.
  • Familiarity with multi-particle collision dynamics.
  • Basic proficiency in analyzing impact lines in collision scenarios.
NEXT STEPS
  • Study the principles of multi-particle collision dynamics.
  • Learn about the coefficient of restitution in different collision scenarios.
  • Research momentum conservation techniques for systems with multiple particles.
  • Explore graphical methods for analyzing collision impact lines.
USEFUL FOR

Hi friends,
I have an issue in solving a Collision of multiple particles.
Please Help me in solving this.
Thank you all in advance.

The problem is as:

Friends according to me the answer should be e = 1, which is not any option and question says answer is 2/3 which is Option (a). Please try to help me in this.
I will appreciate the help.

The method you applied is applicable for two particle collision only. You'll need to do adjustments before applying this method.

Well if I'll conserve momentum for the whole system there would be two lines of imapact.
Ok first I'll do some adjustment in that and then will continue.
