Homework Help: Friction problem help

  1. Jun 13, 2010 #1
    1. The problem statement, all variables and given/known data

    You need to move a 500 N box across the floor. You pull on the box with a rope which is also horizontal. The floor is not frictionless. You move the box so that it moves with a constant v of 3m/s by applying a 200 N force.

    Coefficient of Friction?

    Also,

    same question except pull the box at an angle of 30 degrees from the horizontal, use 0.4 coefficient.

    what is the tension in the rope

    3. The attempt at a solution

    I just really cant even get started on this one, i have no idea, my professor really didnt cover to much of this but gave us 4 similar questions on it, any help would help me out....
