What is the acceleration of a block in this scenario?

Click For Summary

Homework Help Overview

The discussion revolves around determining the acceleration of a block in a physics problem. The original poster expresses confusion regarding the derivation of the acceleration value, which they believe to be 0.5 m/s², and questions the reasoning behind it.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss the force equations and the reasoning behind the acceleration calculation. There is a focus on understanding the direction of the acceleration and the implications of the sign of the result.

Discussion Status

Some participants have offered insights into the relationship between forces and acceleration, while others are exploring the implications of coordinate systems and the direction of forces. The conversation reflects a mix of realizations and ongoing questions about the problem setup.

Contextual Notes

The original poster indicates that the question is for personal learning and will not be graded, which may influence the nature of the discussion. There is also mention of a specific answer choice that is not directly addressed in the conversation.

Homework Statement



Okay, i am preparing for an exam so the questions i am doing are only for my learining they will not be marked anyway

I already know that the answer is C) 0.5ms-2

what i need is an explanation, i don't understand how that answer was derived...

I thought it would be 6N but that wasn't an option

The question is an image attached

Why do you think would it be 6N? Did you form up the force equations?

Please show your work. :smile:

Oh *Face palm* its complicated to explain but i thought this question was asking something else. i now realize how utterly simple it is..

acc= 6/12 nd that's why it's 0.5.. OKay... So how do i know it was going downwards?

wouldn't it be 0.5 upwards since the number is positive? Btw i have many more questions so if your going to stick around i i have a lot more to ask..

It doesn't matter what the sign is, what matters is which way you take your coordinate system. Now the bigger force is obviously acting downwards. So...there you go :wink:
