Homework Help: Pulley quesiton

  1. Mar 23, 2013 #1
    1. The problem statement, all variables and given/known data

    The figure below shows an object on an inclined ramp of mass 0.98kg. The angle of the inclined surface is 32deg with the horizontal. The object on the ramp is connected to a second object of mass 2.13kg on a horizontal surface below an overhang that is formed by the inclined surface. Further, an external force of magnitude 9.00N is exerted on the object on the ramp. We observe both objects to accelerate. Assuming that the surfaces and the pulley are frictionless, and the connecting string and the pulley are massless, what is the tension in the string connecting the two objects?

    [see picture attached]

    2. Relevant equations

    3. The attempt at a solution

    FT+ 5.09N - 9N = 0.98a
    Ft - 3.91 = 0.98a

    -3.91 = -1.155a

    What's your question?

    If you want your solution critiqued, you should show in more detail how you got those quantities.

    Where does the angle of the incline come into play, etc. ?
