String Tension question

  1. Oct 16, 2008 #1
    1. The problem statement, all variables and given/known data
    A 6.0 box is on a frictionless 44 slope and is connected via a massless string over a massless, frictionless pulley to a hanging 1.5 weight.

    1.What is the tension in the string if the 6.0 box is held in place, so that it cannot move?

    2.What is the tension in the string once the box begins to move?

    2. Relevant equations

    3. The attempt at a solution
    I did a free body diagram for the two masses but I missed a day of class and I'm trying to figure out exactly how to set this up to solve it. Any help is appreciated. Thanks

    Hi fronomo,

    What do you free body diagrams look like? For example, what about the force diagram for the 1.5 (kg?) hanging box look like for the first case? What equation can you get from it?
