Homework Help: What is the tension in the rope

  1. Oct 7, 2009 #1
    1. The problem statement, all variables and given/known data

    A horizontal rope is tied to a 23 kg box on frictionless ice. What is the tension in the rope under each of the following conditions

    a) the box is at rest.
    b) the box moves at a steady 5 m/s
    c) the box has Vx= 5 m/s and Ax = 5 m/s^2

    2. Relevant equations

    3. The attempt at a solution
    got 0 for "a". that's right... don't know how to get the other ones.

    Re: Tension

    What's the net force acting on the block when it is at rest? What's the net force when it's moving at constant speed? What's the net force when it's accelerating?

    I am working on this as well. Jay, are you saying that according to Newton's 1st law there C will be 0 as well?
