Calculating Tension in a 6-kg Bucket Being Pulled Up by a String

Click For Summary

Homework Help Overview

The problem involves calculating the tension in a rope pulling a 6-kg bucket of water straight up at a constant speed, which suggests a focus on forces and equilibrium in mechanics.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the tension in the rope, with some suggesting that the tension could be zero due to equilibrium, while others argue that the bucket would fall if that were the case. There is a focus on confirming the calculated tension value of 60 N.

Discussion Status

The discussion is ongoing, with multiple interpretations of the problem being explored. Some participants provide guidance on the reasoning behind the tension calculation, while others express uncertainty about the assumptions being made.

Contextual Notes

Participants are working under the assumption that the bucket is moving at a constant speed, which implies no net acceleration. There is a repeated emphasis on confirming the calculated tension value before submission.

Homework Statement


A 6-kg bucket of water is being pulled straight up by a string at a constant speed.

What is the tension in the rope?

about 42 N
about 60 N
about 78 N
0 N because the bucket has no acceleration.

Homework Equations


[tex]\Sigma[/tex]F=ma
ma=T-mg
T=ma+mg

The Attempt at a Solution



I get about 60 but I want to be sure before I submit this answer. can someone please check my work to make sure i am right?

No its 0N any constant acceleration is in equilibrium therefore the net force is equal to 0. W=FD W=0
 
im looking for the tension and the tension wouldn't be 0 because if it were the bucket would be falling
 
sorry should have read your question better 60N is right for the tension.
