Homework Help Overview

The discussion revolves around a problem involving an Atwood's Machine, where two masses (1.8 kg and 1.2 kg) are connected by a pulley. Participants are tasked with finding the acceleration of the masses and the tension in the string while ignoring friction.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to understand how to calculate acceleration and tension, expressing uncertainty about the relationship between net force and tension. Other participants question which mass is the hanging mass and suggest including both masses in the calculations for acceleration.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the problem. Some have offered partial calculations, while others are clarifying the setup and relationships between the variables involved.

Contextual Notes

There is a mention of an upcoming test, indicating time constraints. Participants are also navigating assumptions about the system, such as the effects of friction and the roles of the different masses.

Homework Statement


In an Atwood's Machine, the larger mass is 1.8kg and the smaller mass is 1.2.
(A)Ignoring friction what is the acceleration of the masses?
(B)What is the tension of the string.

- I know you have to find the acceleration to get the tension but i don't know how to find the acceleration.
I think you replace net force with T-(the mass) ut i am also unsure of why you do that.

Homework Statement



In an Atwood's Machine, the larger mass is 1.8kg and the smaller mass is 1.2.
(A)Ignoring friction what is the acceleration of the masses?
(B)What is the tension of the string.


Homework Equations



Fnet=ma

The Attempt at a Solution



T-1.2g = 1.2a
T = 1.2g + 1.2a
 


which mass is the hanging mass?
 


do you have the answer?
 
sorry...wrong question
 
1.96 m/s^2 is a i think.
 
don't forget to include the 1.8kg mass to get the acceleration
