SUMMARY

The discussion focuses on solving a physics homework problem related to elastic collisions. The user attempts to apply the principles of conservation of momentum and kinetic energy to determine the final velocities of two colliding objects, arriving at v1 = 254.4 m/s and v2 = 46.2 m/s. The user seeks clarification on the assumptions made regarding energy distribution and the definitions of elastic collisions. The conversation emphasizes the importance of setting up simultaneous equations to solve for unknowns in collision scenarios.

PREREQUISITES
  • Understanding of elastic collision principles
  • Knowledge of conservation of momentum
  • Familiarity with kinetic energy equations
  • Ability to solve simultaneous equations
NEXT STEPS
  • Study the definitions and properties of elastic and inelastic collisions
  • Learn how to derive and apply the conservation of momentum in collision problems
  • Explore kinetic energy calculations in different types of collisions
  • Practice solving simultaneous equations in physics contexts
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and collision theory, as well as educators seeking to enhance their teaching methods in these topics.

Tell me why you think you can assume that each piece gets the same amount of energy?

Im not going to lie. I guessed. Wish to give me a better idea of how to tackle this?
 
What is the definition of an elastic collision?

Ah...

so what I have done is conserves ALL of the kinetic energy! This let's me set up some simultaneous equestions with the momentum and all the kinetic energy conserved.

This gives me: v1 = 254.4m/s

and v2 =46.2 m/s.

does this seem correct (i havnt got the answer!) i can post all the workings if that helps.
 
Go ahead and post the work.
