Magnitude of the total momentum of both blocks

Click For Summary
SUMMARY

The discussion focuses on calculating the total momentum of two blocks in a collision scenario, utilizing the principle of momentum conservation. The equation used is p = mv, where p represents momentum, m is mass, and v is velocity. Participants confirm that it is sufficient to calculate the momentum either before or after the collision, as momentum remains constant throughout the event. This understanding simplifies the problem-solving process for students tackling similar physics homework.

PREREQUISITES
  • Understanding of the momentum formula p = mv
  • Knowledge of the conservation of momentum principle
  • Basic skills in analyzing before and after collision scenarios
  • Familiarity with graphical methods for momentum analysis
NEXT STEPS
  • Study the conservation of momentum in elastic and inelastic collisions
  • Explore graphical methods for visualizing momentum before and after collisions
  • Learn how to calculate momentum for multiple objects in a system
  • Investigate real-world applications of momentum conservation in physics
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and collision problems, as well as educators looking for effective methods to teach momentum concepts.

Homework Statement


Find magnitude of momentum of both blocks

Homework Equations


p=mv

The Attempt at a Solution


I am doing my homework right now and just need help understanding finding the total momentum given a before collision/ after collision situation. So i am unsure if i should take the momentum of the whole system from before and after by adding them together and then find the momentum based off of that? That is what i am thinking
Given a before after situation like this

wait since momentum is conserved i think i can just take the momentum of either the before or after part of the collision
 
i just tested it using graphical method and i realized i can use either the momentum of the before or after collision.
 
it does not matter
