Discussion Overview

The discussion revolves around a physics problem involving a boy sitting on a sled with a mass of 100kg, being pulled forward with an average force of 500N over a distance of 20 meters. Participants are exploring concepts related to work, force, and acceleration, seeking assistance with calculations and understanding the underlying principles.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant asks how much work is done when pulling the sled and what the average acceleration is, indicating uncertainty about the calculations.
  • Another participant encourages sharing previous attempts to solve the problem to facilitate assistance.
  • A participant claims to have calculated the average acceleration but expresses uncertainty about how to determine the work done.
  • One participant suggests that work can be calculated as force times distance, implying a straightforward approach to the problem.
  • Another participant confirms the calculation of work as 500N multiplied by 20 meters.

Areas of Agreement / Disagreement

There is no explicit disagreement, but participants are at different stages of understanding and calculation, with some seeking clarification while others provide guidance.

Contextual Notes

Participants have not detailed their assumptions or the steps taken in their calculations, leaving some aspects of the problem unresolved.

A boy is sitting on a sled that is 100kg. If you pull the sled forward for 20 meters, your avg. force is 500N. How much work did you do at that time? (no friction on the ice/snow). What was your avg. acceleration?

Help for Force, Impulse and Momentum Thanks!

hi zmillz18! welcome to pf! :wink:

show us what you've tried, and where you're stuck, and then we'll know how to help! :smile:
 


well i got the avg. acceleration i think..i just need help finding how much work he did, I don't know where to start lol
 


the avg acceleration i got was v1 = .04
 
well, work = force times distance, sooo … ? :smile:
 


so 500N x 20 meters?
 
yup! :biggrin:
