Friction of a sliding mass on a slope

Click For Summary

Homework Help Overview

The discussion revolves around the physics of a mass sliding down a slope, specifically focusing on the role of friction, both static and kinetic. Participants are exploring the forces at play and their relationships to the motion of the mass.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are attempting to relate the concepts of static and kinetic friction to the motion of the mass on the slope. Questions are raised about the normal force and its connection to kinetic friction, as well as the forces acting on the mass.

Discussion Status

The discussion is ongoing, with participants questioning the relationships between different forces and the concepts of friction. Some guidance has been offered regarding the normal force, but there is no explicit consensus on the approach to take.

Contextual Notes

There seems to be an emphasis on the need for participants to make serious attempts at the problem before receiving help, indicating a learning-focused environment. The mention of free body diagrams suggests that visual representations of forces may be relevant to the discussion.

Homework Statement
Under which condition will the sliding stop? Show how you found this condition.
When the sliding stops, what distance will be traveled since t=0?
Relevant Equations
At t=0, its velocity is V0

Could you please help me with this? I guess move of the mass will be determined with kinetic friction.

Static friction is N=mg*costheta as far as I know.

That's the normal force due to gravity. How is kinetic friction related to that.

Also, have you learned about free body diagrams?
 
What force is sliding it down the ramp and what is that force equal to if the block is stopped?
