My setup is same but it's not perfectly inelastic it's just head on inelastic
Velocity of spheres after collision
Click For Summary
Homework Help Overview
The problem involves three spheres, each of mass m, on a frictionless surface. Spheres A and B are connected by a cord and initially at rest when sphere C strikes sphere B. The task is to determine the velocities of the spheres after the collision, assuming an elastic impact between B and C.
Discussion Character
- Mixed
Approaches and Questions Raised
- Participants discuss the conservation of momentum and energy, questioning the assumptions about the directions of velocities and the effects of the inextensible cord. Some suggest using vector equations for momentum conservation, while others explore the implications of the elastic collision.
Discussion Status
The discussion is active, with various approaches being explored. Participants have raised concerns about the assumptions made regarding the velocities of spheres A and B, and some have suggested alternative methods such as using the coefficient of restitution instead of energy conservation. There is no explicit consensus, but several equations and relationships have been proposed.
Contextual Notes
Participants note the complexity of the problem, with multiple unknowns and equations being discussed. The nature of the collision (elastic vs. inelastic) is also a point of consideration, with implications for how to approach the problem mathematically.
