Dynamics: Collision with inclined plane

Click For Summary
SUMMARY

The discussion centers on the conceptual understanding of momentum conservation in dynamics, specifically regarding a collision with an inclined plane. The participant correctly identifies that momentum is not conserved due to the force exerted by the inclined plane, which acts perpendicular to its surface. The participant also notes the importance of clearly defining the coordinate system (x, y directions) to enhance understanding. The quality of the attachment provided for the solution is questioned, indicating a need for clarity in visual representation.

PREREQUISITES
  • Understanding of basic physics concepts, particularly momentum and forces.
  • Familiarity with inclined planes and their effects on motion.
  • Knowledge of coordinate systems in physics.
  • Ability to create clear diagrams to represent physical scenarios.
NEXT STEPS
  • Research the principles of momentum conservation in non-isolated systems.
  • Learn about the forces acting on objects on inclined planes.
  • Study how to effectively represent physics problems using diagrams.
  • Explore advanced dynamics topics, such as collisions and energy transfer.
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in understanding the dynamics of collisions and the role of forces in momentum conservation.

Homework Statement


15-73.png

I have two conceptual questions that I have written in read in my solution. The solution, and all the work, is correct. However there are two things that I am unsure as to why I am doing it. Thanks!

Homework Equations



Included in solution, although none should be needed as questions are conceptual.

The attachment is well under the limit, I don't know why the quality is be lowered so drastically...

Can read the momentum question. With difficulty.
Momentum isn't conserved because the plane exercises a force. Since it is smooth, it can only exercise a force perpendicular to its surface. Along the incline no force, so momentum conservation. Can't distinguish what your x, y, directions are. Make a better picture or type it out.
