Homework Help Overview

The discussion revolves around determining the weight of a person riding on a chair that was pushed with a force of 82N. The chair's weight is given as 135N, and the distance traveled is 1.5 meters. Participants are exploring the necessary information and calculations needed to find the person's weight and the chair's acceleration.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants suggest determining the coefficient of friction and question the initial conditions of the chair's movement, such as its speed and whether it started from rest. They also inquire about the presence of friction and its impact on the calculations.

Discussion Status

The discussion is active, with participants offering guidance on factors to consider, such as friction and initial velocity. Multiple interpretations of the problem are being explored, particularly regarding the role of friction in the calculations.

Contextual Notes

There is a mention of the possibility of experimenting with the chair to gather additional information, indicating that the original poster is allowed to conduct tests to aid in their calculations.

A chair was pushed with a force of 82N with a person riding on it. The chair traveled 1.5 meters, and the chair weighs 135 N. I need to know the weight of te person who was riding the chair, and the acceration of the chair. I am allowed to experiment with the chair to gather any additional information, so if i nee to know anything can you please tell me what I need and how to find it? And then what i should do with the newly gathered information to get my answer? Thanks!

You need to figure out the coefficient of friction. Once you have this, just use your work formulas to figure it out.
 
Do you know how fast the chair was traveling at the end of the 1.5 m? Did is start from rest? Do you know how long it took to travel that distance? Would either of those quantities matter?
 
was there any friction? or are u juz working on non-frictionless surface? You certainly nid the coefficient of friction if there is friction and the friction force acting on the chair.. before formulas can be applied to solve for the weight of the person.
