System of equations with acceleration and tension

  1. Mar 11, 2016 #1
    1. The problem statement, all variables and given/known data
    So there is a pulley with 1 mass hanging from it. The string is wrapped around and one end is taped to the pulley so that only one end of the string hangs from the pulley. There is a mass of 100 grams attached to that string. Create a system of equations to find linear acceleration of the descending mass and the tension in the string connecting the mass to the disk.

    2. Relevant equations
    F=ma

    3. The attempt at a solution
    The first equation would be T=mg-ma because the body is falling downward. How would i find the other equation with T and a to help me create a system of equations

    Do you have any information about the pulley?
