Elastic collision find final velocity 8.39

Click For Summary

Homework Help Overview

The problem involves an elastic collision between two gliders of different masses moving towards each other on a frictionless air track. The original poster seeks to determine the final velocities of both gliders after the collision.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • The original poster attempts to apply the principle of conservation of momentum but expresses difficulty in maintaining their approach. Some participants note that both momentum and kinetic energy are conserved in elastic collisions.

Discussion Status

Participants have provided guidance on the conservation laws applicable to the problem. The original poster is exploring their understanding of the equations needed to solve for the final velocities, and there is an acknowledgment of the need for two equations to find the two unknowns.

Contextual Notes

The original poster mentions a specific direction for the final velocities, indicating assumptions about the motion post-collision. There may be constraints related to the problem setup that have not been fully articulated.

A glider of mass 0.147 kg is moving to the right on a frictionless, horizontal air track with a speed of 0.720m/s . It has a head-on collision with a glider 0.309 kg that is moving to the left with a speed of 2.26 m/s. Suppose the collision is elastic. Find the magnitude of the final velocity of the 0.147 glider. Find the magnitude of the final velocity of the 0.309 glider.

So fa all that I know is that both of the gilders will go in the direction of the left when they coliide. I started my problem thinking that i could add the momentum of the gliders together and go from there but i am haveing trou

Collision is elastic so kinetic energy is conserved and so is momentum.
 
anything else that can hellp me?
 
That's all you really need I believe,you'll get two equations with two unknowns and you can solve.
