Hard kinematics problem: Block pushed onto a moving conveyor belt

Click For Summary
SUMMARY

The discussion focuses on solving a kinematics problem involving a block being pushed onto a moving conveyor belt. Key points include the necessity of defining the coefficient of friction (denoted as ##\mu##) and understanding the equations of motion in the belt frame. Participants emphasize the importance of vector components and the relationship between friction and deceleration, specifically that the deceleration due to friction is given by ##a = \mu g##. The conversation highlights the need for careful consideration of signs in vector components and the geometric approach to minimize velocity.

PREREQUISITES
  • Understanding of kinematics and motion equations
  • Familiarity with vector addition and components
  • Knowledge of friction and its role in motion (##\mu## coefficient)
  • Ability to analyze motion in different reference frames (belt frame vs. ground frame)
NEXT STEPS
  • Study the equations of motion in non-inertial reference frames
  • Learn about vector decomposition in physics problems
  • Explore the implications of friction on motion dynamics
  • Review geometric approaches to solving kinematics problems
USEFUL FOR

Students and professionals in physics, particularly those studying mechanics, engineers working with conveyor systems, and anyone interested in advanced kinematics problems.

That's a quite a hard problem I think. You can't just guess that the answer is ##g/2## or ##3g/13## or whatever. You have to work it out.
Well I took the component of mg acting on rod but I doubt it's a right approach.
