Homework Help: Finding tension in a rope

  1. Dec 18, 2012 #1
    1. The problem statement, all variables and given/known data
    A bucket is lifted up by a rope, slowing down at a constant rate of 0.640 m/s^2. Find the tension in the rope if the bucket weighs 22.0 N.

    2. Relevant equations
    Fg(gravity)=M*G(gravitational force)

    3. The attempt at a solution
    9.8 m/s^2 + 0.640 m/s^2 = 10.44 m/s^2
    M=2.24 kg

    Ft=2.24 kg * 10.44 m/s^2
    Ft=23.39 N

    Everything is all scrambled up. Why are you adding accelerations? Draw a force diagram. The tension T points up, the weight W points down and you know the acceleration. Try and solve for T.
