Hard kinematics problem: Block pushed onto a moving conveyor belt

Click For Summary

Homework Help Overview

The discussion revolves around a kinematics problem involving a block being pushed onto a moving conveyor belt. Participants are exploring the dynamics of motion, friction, and vector components in this context.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning, Problem interpretation, Assumption checking

Approaches and Questions Raised

  • Participants discuss the implications of a coefficient of friction, the relationship between velocities, and the need for a diagram. There are attempts to express motion in terms of vector components and questions about the effects of friction on motion.

Discussion Status

The discussion is active with participants sharing various approaches and questioning assumptions about the forces at play. Some guidance has been offered regarding the representation of motion in different frames of reference, and there is an ongoing exploration of the correct signs for velocity and acceleration components.

Contextual Notes

Participants note the absence of specific numerical values for the coefficient of friction and the need to clarify the relationship between the block's motion and the conveyor belt's speed. There is an emphasis on adhering to forum rules that limit the provision of direct solutions.

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.
