Homework Help Overview

The problem involves calculating the net work done on a mincemeat pie sliding down an inclined ramp, incorporating concepts of forces, friction, and work in a physics context.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to identify the net force acting on the pie and how to incorporate the coefficient of kinetic friction into their calculations. Some participants suggest drawing a free body diagram and summing the forces as a way to approach the problem.

Discussion Status

Participants are actively engaging with the problem, with some guidance provided regarding the use of free body diagrams and summing forces. There is uncertainty expressed by the original poster about their understanding and calculations, indicating an ongoing exploration of the concepts involved.

Contextual Notes

The original poster mentions being new to the unit, which may affect their familiarity with the concepts and methods required to solve the problem. There is also a lack of consensus on the correctness of the calculated work value presented by one participant.

This is the question I am given:

The largest mincemeat pie ever created had a mass of 1.020 x 10³ kg. Suppose that a pie with this mass slides down a ramp that is 18.0m long and is inclined to the ground by 10.0°. If the coefficient of kinetic friction is 0.13, what is the net work done on the pie during its decent.

Ok, we just started this unit. So I know the equation for work. the displacement is 18m and the angle is 10.0°. What do I do to get the net force and how do I make the coefficient come into this problem.

since you are on to work then you know how to sum forces correct? Draw out the free body diagram, sum forces, once you have the forces summed I think you know where to go with it. If not let me know.
 
no i don't think I am gettin it. can u give a few more clues. thx
 
ok I am gettin 327.23 J but i highly doubt it's right
