Elastic Collision between ball and pivoted rod

Click For Summary
SUMMARY

The discussion centers on the analysis of an elastic collision between a ball and a pivoted rod, referencing a specific solved problem from MIT's materials. The participants confirm that while energy and angular momentum are conserved during the collision, linear momentum cannot be conserved due to the external force acting on the system at the pivot point. The coefficient of restitution is established as e=1, indicating a perfectly elastic collision.

PREREQUISITES
  • Understanding of conservation of energy principles
  • Knowledge of angular momentum conservation
  • Familiarity with the concept of the coefficient of restitution
  • Basic mechanics involving external forces in collision scenarios
NEXT STEPS
  • Study the principles of conservation of linear momentum in non-isolated systems
  • Explore the implications of the coefficient of restitution in various collision types
  • Investigate the dynamics of pivoted rods in collision scenarios
  • Review advanced problems involving elastic and inelastic collisions
USEFUL FOR

Physics students, educators, and anyone interested in mechanics, particularly those studying collision dynamics and energy conservation principles.

Homework Equations

The Attempt at a Solution


In the solution, they conserve energy and angular momentum. Can I conserve linear momentum? Also, can I use coefficient of restitution (as e=1)?
 
Physics news on Phys.org
I think we can not conserve linear momentum because if we consider rod and ball as a system then an external force acts on it(at P). But we can use e=1 here.
