Calculating Force of Friction: 36N Applied to 6kg Cart with 5.5m/s Acceleration

Click For Summary

Homework Help Overview

The discussion revolves around calculating the force of friction acting on a 6 kg cart that is subjected to a 36 N applied force while accelerating at 5.5 m/s². Participants express uncertainty about the relevant concepts and calculations involved in determining the force of friction.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants question how to calculate the net force required for the cart's acceleration and express confusion about the relationship between applied force, friction, and acceleration. Some mention using the formula F = ma but are unsure how to apply it correctly.

Discussion Status

The discussion is ongoing, with various participants attempting to clarify the concepts of net force and friction. Some guidance has been offered regarding the use of F = ma, but there is no explicit consensus on the correct approach or solution yet.

Contextual Notes

Participants indicate a lack of understanding of key terms and formulas, which may hinder their ability to progress in solving the problem. There is also mention of homework constraints that may limit the resources available for assistance.

stupid forces of friction !

1. a force of 36N is applied to a 6kg cart. If the cart accelerates at 5.5m/s what is the force of fricrion



im not even sure what to do, I am in physics 20 and not very good at it please help this is my atempt



Ffriction=Fn*u idk what anthing means? haha please help ?

it dosent tell me a net force, i have no idea what to go. i tried f=umg but it didnt come out right i know the answear is 3 i just don't know how toget there
 


Find the net force using F=ma.
Try to go from there

Use F = ma. What should be F then? How will F get that value?
