Homework Help Overview

The discussion revolves around a problem involving tension distribution in a multi-block system being pulled by a rope. The original poster describes a scenario with three blocks of varying weights and seeks to understand the tension in the ropes connecting them.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the forces acting on the blocks and the tension in the ropes, with some providing specific values for the tension. There is also a correction regarding the units of weight, indicating a potential misunderstanding of the problem setup.

Discussion Status

Some participants have offered specific values for the tension in the ropes, while others have questioned the correctness of the weight units used in the problem. There is an ongoing exploration of how these factors influence the tension calculations.

Contextual Notes

There is a noted confusion regarding the units of weight, with participants clarifying that the weights should be in kilograms rather than Newtons, despite the original poster's mention of forces in Newtons. This discrepancy may affect the understanding of the problem.

Ok - I was helping a friend out and was helping her with a problem but I am not sure if i was right.
A girl is pulling three blocks with a rope at a force of 6 N . There is two more strings between each block. The first block weighs 0.5 N the second block weighs 1.5N the third block weighs 1 N. Ignore friction. What is the amount of tension on each rope? :confused:

Sorry i made a mistake the weight of the blocks are meant to be in kilograms not N .
lol idiot me...
 
The force on the rope between the first and second blocks is 5N
And the force on the rope between the second and third blocks is 2N.

I hope that helps
If you need the steps to get the answers, just ask.

The unit of weight IS Newton, though..
