What is the magnitude of force of friction of the snow

Click For Summary

Homework Help Overview

The discussion revolves around determining the magnitude of the force of friction acting on a sled being pulled across a horizontal snow surface at a constant velocity. The original poster expresses uncertainty about how to approach the problem, particularly regarding the application of forces and vector components.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the need to understand vector components and the normal force. The original poster attempts to calculate the normal force using the applied force and its angle but feels stuck. Others question the necessity of the normal force in this scenario and prompt consideration of the net force acting on the sled.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the problem. Some guidance has been offered regarding the components of forces, but there is no explicit consensus on the next steps or the correct approach to finding the force of friction.

Contextual Notes

The original poster mentions preparing for a test, indicating a time constraint. There is also a suggestion that the problem may not require the normal force, which introduces a potential misunderstanding of the problem setup.

seld pulled at a constant velocity acroos a horizontal snow surface, if force 80 apploed to the sled rope at an angle of 53 to the ground,
what is the magnitude of force of friction of the snow?
i don't know how to solve it
i have test 2morrow
i need some explanition plez

First, please stop writing in "texting" shorthand. It's not Youtube here.

And get used to the other rules: we are not here to answer your homework questions for you. You must show some of your effort before we help you. Do you have a textbook? Read a bit about components of vectors, and coefficient of friction, and normal force.
 
i read the whole chapter and i still don't get it
i know the compnents of vector
first step i think
to get normal force::
80(cos53)
and you get
48 N
and I'm stuck!
i know that i have to find the coffecient of the friction
so i can get Ff
that's not a homework, I'm studying for a test
thanks
 
This is not on a slope. You don't need the normal force here, actually. You need to know a few other things.

What's the net force on this object if it is pulled at a constant velocity?
 
isn't 0..
