Homework Help: Lifting a Bucket please check my work

  1. Apr 25, 2010 #1
    1. The problem statement, all variables and given/known data
    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.

    2. Relevant equations
    [tex]\Sigma[/tex]F=ma
    ma=T-mg
    T=ma+mg

    3. 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.
