Newtons Laws applyied to pulleys

  1. Oct 4, 2009 #1
    1. The problem statement, all variables and given/known data
    There is a drawing with a block weight 416N on a table attached to a string that is running through a pulley at the end of the table. On the other end of the string a block that is hanging off the side of the table with a weight of 215N. Ignore all frictional effects and assume the pulley is massless. Find the acceleration of the 2 blocks and the tension of the cord.


    2. Relevant equations
    EF = ma
    EFx = the sum of all the forces in the x direction
    EFy= the sum of all the forces in the y direction


    3. The attempt at a solution
    I attempted to draw the free body diagram with all the forces labeled including the normal force, weight, and tension.

    If you can show or describe your FBD for each mass, someone will help you write the sum-of-forces = ma equation for each diagram.
