Tension of a string between 2 blocks of equal mass on a flat surface

Click For Summary

Homework Help Overview

The problem involves determining the tension in a string connecting two blocks of equal mass that are being pulled by a force of 17 Newtons. The context is rooted in classical mechanics, specifically Newton's laws of motion.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the necessity of drawing free body diagrams (FBDs) for each block to analyze the forces acting on them. There are mentions of applying Newton's Second Law and setting up equations based on the system's acceleration.

Discussion Status

The discussion is ongoing, with some participants providing guidance on the importance of showing work and using diagrams. There is an emphasis on understanding the problem rather than simply providing answers, indicating a collaborative environment aimed at deeper comprehension.

Contextual Notes

Participants highlight the need for clarity in the approach to the problem, suggesting that assumptions about the system's behavior and the equal mass of the blocks are critical to the analysis.

Attempt at a solution is not just 17... haha... Show your equations that you used, so we can help you... Did you draw your FBD's for the 2 masses?
 
Very easy once you have done the equations for both the masses...
 
This is a very straight forward problem.

Newton's Second Law!

If you draw a free body diagram of each block you will have:

ƩFBLOCK1=ma

FPULL - T = ma

ƩFBLOCK2=ma

T = ma

----

You are given that the masses are equal to each other and the system will accelerate at the same rate!
 
Yes Bill Nye Tho, for you it is very easy, but the purpose of this forum is to help people understand what they deal with by letting them do the problem themself, we just aid them when they struggle... Try helping not just showing that you know the answer...
