Finding the maximum displacement

Click For Summary
SUMMARY

The discussion focuses on calculating the maximum displacement of block A after a bullet escapes with a velocity of 100 m/s. The user initially applied the impulse-momentum theorem to determine the velocities of both blocks and then used the work-energy theorem, assuming negligible work done by internal dissipative forces. However, this assumption led to an incorrect result, indicating a need for reevaluation of the approach to account for dissipative forces in the system.

PREREQUISITES
  • Understanding of the impulse-momentum theorem
  • Familiarity with the work-energy theorem
  • Knowledge of internal dissipative forces in physics
  • Basic principles of kinematics and dynamics
NEXT STEPS
  • Review the principles of the impulse-momentum theorem in detail
  • Study the work-energy theorem and its applications in systems with dissipative forces
  • Learn about energy conservation in collision scenarios
  • Explore examples of maximum displacement calculations in physics problems
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and dynamics, as well as educators seeking to clarify concepts related to displacement and energy conservation in systems involving collisions.

Homework Statement

I want to find the maximum displacement of block A in the left direction

Homework Equations

The Attempt at a Solution



I first found the velocities of both blocks after the bullet escapes with 100m/s by using the impulse-momentum theorem.
I then applied the work-energy theorem for the system
For a maximum displacement, I assumed that work done by internal dissipative forces must have been tending to zero. Solving, I got an answer much greater than the correct answer which means my assumption was wrong.

I don't know how to proceed further
