Homework Help: Pulley Acceleration Question

  1. Sep 29, 2009 #1
    1. The problem statement, all variables and given/known data

    Two masses, 1.98 kilograms and 2.68 kilograms, are attached to a lightweight cord that passes over a pulley as shown below.

    What is the acceleration of the smaller mass? Hint: For a system of connected objects, the unbalanced external force acts on the mass of the entire system.

    2. Relevant equations



    3. The attempt at a solution


    4.66kg(9.8)=45.668 N

    45.668N/1.98kg = 23.1 m/s/s

    Is this correct?
