Homework Help: Tension on a rope-no idea how to even start.

  1. Feb 5, 2009 #1
    Tension on a rope--no idea how to even start.

    1. The problem statement, all variables and given/known data
    A rope is used to pull a 10kg block across the floor with an acceleration of 3m/s^2. If the frictional force on the black is 50 N, what is the tension on the rope?
    M=50kg
    A= 3m/s^2
    Frictional force is 50 N.

    2. Relevant equations
    F=ma


    3. The attempt at a solution
    In truth, I have no idea where to even start with this question. Though I did begin by drawing a free-body diagram, but that got me nowhere.

    I take it M=50kg is a typo?

    Anyway, your FBD - what did it look like? Which forces pointed in what direction?
