Two Masses, a Pully, and an Inclinde Plane

  1. Oct 17, 2007 #1
    1. The problem statement, all variables and given/known data

    Block 1, of mass m1 = 0.700kg , is connected over an ideal (massless and frictionless) pulley to block 2, of mass m2. Assume that the blocks accelerate downword with an acceleration of magnitude = 0.250m/s^2 and that the coefficient of kinetic friction between block 2 and the plane is u = 0.200.

    Tried to attach a good picture of the angle at which the block is 30

    2. Relevant equations


    With T=6.69
    F=un Which n=8.5 so then it would be 1.7

    3. The attempt at a solution

    well to set it up im not sure if im right but i tried to sub all know values into the above eq


    i keep geting wrong answer + i dont konw how to solve when M2 is on both sides? What do i do. I know the answer has to be smaller than .700kg because if it were larger they would not move.

    Good. That's Newton's 2nd law applied to mass 2. Do the same for mass 1.

    How do you know the tension?
