Finding net force and net acceleration

Click For Summary

Homework Help Overview

The discussion revolves around calculating the net force and net acceleration of a hamburger sliding down a ramp inclined at 45 degrees, considering the mass of the hamburger and the coefficient of kinetic friction. Participants are exploring the dynamics of forces acting on the object in this context.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the need to identify the component of gravitational acceleration acting down the ramp and question whether the object is in equilibrium. There is mention of using a free body diagram to analyze forces rather than relying solely on the formula for net force.

Discussion Status

The discussion is ongoing, with participants providing guidance on using free body diagrams to approach the problem. There are multiple interpretations regarding the state of equilibrium and the forces involved, indicating a productive exploration of the topic.

Contextual Notes

Participants are operating under the constraints of a homework assignment, which may limit the information they can use or the methods they can apply. The specific values for gravitational acceleration and friction are noted, but their application in the context of the problem remains under discussion.

Homework Statement


A hamburger with a mass of 2500 kg was slided down a ramp that has a 45 degree incline, and the coefficient of kinetic friction between the hamburger and the ramp is .597. What is the net force acting on the hamburger? What is the net acceleration?

Homework Equations


Mass of burger= 2500 kg
mew k = .597

The Attempt at a Solution


The net force is mass times acceleration. But i don't have acceleration.

You have the acceleration due to gravity and the force due to friction. You have to find the component of the acceleration due to gravity which points down the ramp.
 
but I'm not sure if the object is at equilibrium?

Have you drawn a free body diagram? Use that to find the net force, not F=ma.
