Physics using Tension

  1. Sep 30, 2008 #1
    1. The problem statement, all variables and given/known data

    A block with a mass of 5.37 kg is placed at rest on a surface inclined at an angle of 46.0° above the horizontal. The coefficient of static friction between the block and the surface is 0.580, and a force of magnitude pushes upward on the block, parallel to the inclined surface. The block will remain at rest only if is greater than a minimum value, Fmin, and less than a maximum value,
    a)Fmax.
    b)Calculate Fmin.


    2. Relevant equations
    SigmaF = ma


    3. The attempt at a solution

    I really have no clue where to start here. Help please.

    Whenever you have a problem involving friction the first step is almost always to draw a free body diagram.
